In this grab taken from video provided by the Thai Navy Seal, a view of the boys and their soccer coach as they are rescued in a cave, in Chiang Rai in Thailand, Monday, 2 July 2018. Rescuers found all 12 boys and their soccer coach alive deep inside a partially flooded cave in northern Thailand late Monday, more than a week after they disappeared and touched off a desperate search that drew international help and captivated the nation. Photo: APA top Thai official said Tuesday that heavy rains forecast for the coming days could worsen floods in the mountain cave where 12 boys and their soccer coach were located after being missing for more than a week, forcing authorities to speed up their extraction.The 13 were located by rescue divers late Monday night in the cave in northern Chiang Rai province during a desperate search that drew international help and captivated the nation. Officials said Tuesday that the boys, aged 11-16, and their 25-year-old coach were mostly in stable medical condition and have received high-protein liquid food.Interior Minister Anupong Paojinda, a member of the country’s ruling military junta, said Tuesday that the boys may need to swim out using diving equipment ahead of bad weather forecast for later in the week. He said the boys would be brought out via the same complicated route through which their rescuers entered.While efforts to pump out the floodwaters would continue, Anupong said it’s clear some areas of the sprawling cave cannot be drained and that in order to get out, the boys may need to use diving gear while being guided by two professional divers each. He conceded that if something went awry, it could be disastrous.”Diving is not easy. For people who have never done it, it will be difficult, unlike diving in a swimming pool, because the cave’s features have small channels,” he said. “If something happens midway, it could be life-threatening.”Video released early Tuesday by the Thai navy showed the boys in their soccer uniforms sitting on a dry area inside the Tham Luang Nang Non cave above the water as a spotlight from a rescuer illuminated their faces.In this grab taken from video provided by the Thai Navy Seal, a view of the boys and their soccer coach as they are rescued in a cave, in Chiang Rai in Thailand, Monday, 2 July 2018.

Photo: APChiang Rai provincial Gov. Narongsak Osatanakorn said the health of the boys and coach were checked using a field assessment in which red is critical condition, yellow is serious and green is stable.”We found that most of the boys are in green condition,” he said. “Maybe some of the boys have injuries or light injuries and would be categorized as yellow condition. But no one is in red condition.”Cave rescue experts have said it could be safer to simply supply them where they are for now, rather than attempting to have the boys dive out. That could take as long as months, however, given that Thailand’s rainy season typically lasts through October.Family members who have kept vigil at the mouth of the cave since their ordeal began June 23 rejoiced at the news that their boys and their coach had been found.”I want to give him a hug. I miss him very much,” said Tham Chanthawong, an aunt of the coach. “In these 10 days, how many million seconds have there been? I’ve missed him every second.”Rescue divers had spent much of Monday making preparations for a final push to locate the missing, efforts that had been hampered much of the week by flooding that made moving through tight passageways filled with muddy water difficult.A pair of expert cave divers from Britain found the group about 300-400 meters (yards) past a section of the cave on higher ground that was thought to be where they might have taken shelter.In the five-minute navy video, the boys are seen wearing their soccer uniforms and are calm, curious and polite. They are also keen to get some food.After an initial exchange in which a rescuer ascertains that all 13 are present, one of the boys asks what day it is, and a rescuer replies: “Monday. Monday. You have been here – 10 days.”The rescuer tells them “you are very strong,” but soon the traditional reserve of Thai children toward adults breaks a bit, and one tells another in Thai, “Tell them we are hungry.””We haven’t eaten,” a boy says in Thai, then breaks into English: “We have to eat, eat, eat!” A fellow boy tells him they already said this, and then the rescuer assures them that “Navy SEALs will come tomorrow, with food and doctors and everything.” At the end of the video a boy asks in English, “Where do you come from?” The rescue diver replies, “England, UK.”Narongsak said Tuesday that the missing were given high-protein liquid food, painkillers and antibiotics. He said doctors had advised giving the medicine as a preventative measure.He said officials had met and agreed on the need to “ensure 100 percent safety for the boys when we bring them out.””We worked so hard to find them and we will not lose them,” he said.In this grab taken from video provided by the Thai Navy Seal, a view of the boys and their soccer coach as they are rescued in a cave, in Chiang Rai in Thailand, Monday, 2 July 2018.

Photo: APAnmar Mirza, a leading American cave rescue expert, said many challenges remain for the rescuers. He said the primary decision is whether to try to evacuate the boys and their coach or to supply them in place.”Supplying them on site may face challenges depending on how difficult the dives are,” Mirza, coordinator of the US National Cave Rescue Commission, said in an email. “Trying to take non-divers through a cave is one of the most dangerous situations possible, even if the dives are relatively easy.”The British Cave Rescue Council, which has members taking part in the operation, said in a statement that “although water levels have dropped, the diving conditions remain difficult and any attempt to dive the boys and their coach out will not be taken lightly because there are significant technical challenges and risks to consider.”Joining the British are other cave experts from around the world and teams from the US, Australia, China and elsewhere.Authorities said efforts would also continue outside the cave, where teams have been scouring the mountainside in search of other entrances to the caverns below. Several fissures have been found and teams have explored some, though so far none have led to the trapped boys.

(Phys.org)—An international team of astronomers reports the discovery of a giant planet and a brown dwarf in a close binary system designated HD 87646. The findings, described in a paper published Aug. 11 on arXiv.org, reveal that HD 87646 is the first close binary system with more than one substellar circum-primary companion known to date.

It is the first close binary system with more than one substellar circum-primary companion discovered to the best of our knowledge. The detection of this giant planet was accomplished using the first multi-object Doppler instrument (KeckET) at the Sloan Digital Sky Survey (SDSS) telescope. Subsequent radial velocity observations using ET at Kitt Peak National Observatory, HRS at HET, the “Classic” spectrograph at the Automatic Spectroscopic Telescope at Fairborn Observatory, and MARVELS from SDSS-III confirmed this giant planet discovery and revealed the existence of a long-period brown dwarf in this binary. HD 87646 is a close binary with a separation of ∼22 AU between the two stars, estimated using the Hipparcos catalogue and our newly acquired AO image from PALAO on the 200-inch Hale Telescope at Palomar. The primary star in the binary, HD 87646A, has Teff = 5770±80K, log(g)=4.1±0.1 and [Fe/H] = −0.17±0.08. The derived minimum masses of the two substellar companions of HD 87646A are 12.4±0.7MJup and 57.0±3.7MJup. The periods are 13.481±0.001 days and 674±4 days and the measured eccentricities are 0.05±0.02 and 0.50±0.02 respectively. Our dynamical simulations show the system is stable if the binary orbit has a large semi-major axis and a low eccentricity, which can be verified with future astrometry observations.

The primary star in the system, HD 87646A, is about 12 percent more massive than the sun and has a radius of about 1.55 solar radii. The system has a separation of only 22 AU between the two stars.A team of researchers, led by Bo Ma of the University of Florida, has been observing HD 87646 since 2006 using a set of telescopes. The scientists employed the W.M. Keck Exoplanet Tracker (KeckET), at the Sloan Digital Sky Survey (SDSS) 2.5m telescope, mounted on the Apache Point Observatory in New Mexico to reveal the presence of a new giant planet that received designation HD 87646b. KeckET is a new generation multiple object Doppler instrument, capable of simultaneously observing more than 50 stars.The planetary status of HD 87646b was confirmed thanks to the radial velocity observations conducted by utilizing the Kitt Peak National Observatory (KPNO) in Arizona, the High-Resolution Spectrograph at the Hobby-Eberly Telescope (HET) in Texas, the “Classic” spectrograph at the Automatic Spectroscopic Telescope, mounted on the Fairborn Observatory in Arizona and the Multi-object APO Radial Velocity Exoplanet Large-area Survey (MARVELS) at SDSS. Moreover, these observations allowed the researchers to detect new even larger companion in the system – a brown dwarf designated HD 87646c.”Our SDSS MARVELS pilot survey and additional observations at the HET, KPNO 2.1m telescope, and Fairborn Observatory confirm the detection of two massive substellar companions in a close binary system HD 87646,” the team wrote in the paper.According to the study, HD 87646b has a minimum mass of about 12.4 Jupiter masses and an orbital period of approximately 13.5 days. HD 87646c is much more massive, having 57 Jupiter masses and much longer orbital period, circling the star every 673 days.The team also conducted dynamical simulations of the system, which allowed them to draw conclusions that HD 87646 is stable if it has a large binary semi-major axis and a relatively low binary eccentricity.However, the question of how this system was formed still baffles the authors of the paper. Given the fact that HD 87646 is the first known system to have two massive substellar objects orbiting a star in a close binary and the masses of the two objects are close to the minimum masses for burning deuterium and hydrogen, these peculiarities raise questions about the system’s formation and evolution.”The large masses of these two substellar objects suggest that they could be formed as stars with their binary hosts: a large molecular cloud collapsed and fragmented into four pieces; the larger two successfully became stars and formed the HD 87646 binary, and the other smaller ones failed to form stars and became the substellar objects in this system. This scenario might be relevant for the binary stars but seems problematic for the two substellar objects on orbits within one AU because it is unclear whether fragmentation on such a small scale can occur,” the paper reads.Other hypothesis offered by the scientists is that the two newly discovered giant objects were formed like giant planet in a protoplanetary disk around HD 87646A. However, they added that such massive disks are rare in close binaries, and further investigation is needed to confirm this explanation.
