Aug. 27, 2021 Brown dwarfs are astronomical objects with masses between those of planets and stars. The question of where exactly the limits of their mass lie remains a matter of debate, especially since their ...
Feb. 17, 2022 A team of astronomers has discovered a rare pair of brown dwarfs that has the widest separation of any brown dwarf binary system found to date. They're 12 billion miles apart, or three times the ...
Apr. 8, 2021 Astronomers have discovered the most rapidly rotating brown dwarfs known. They found three brown dwarfs that each complete a full rotation roughly once every hour. That rate is so extreme that if ...
Dec. 13, 2023 Brown dwarfs are objects that straddle the dividing line between stars and planets. They form like stars, growing dense enough to collapse under their own gravity, but they never become dense and hot ...
June 9, 2022 Brown dwarfs, mysterious objects that straddle the line between stars and planets, are essential to our understanding of both stellar and planetary populations. However, only 40 brown dwarfs could be ...
July 7, 2022 How often do stars live alone? For brown dwarfs -- objects that straddle the boundary between the most massive planets and the smallest stars -- astronomers need to uncover more examples of their ...
Mar. 23, 2022 White dwarfs were once normal stars similar to the Sun but then collapsed after exhausting all their fuel. These interstellar remnants have historically been difficult to study. However, a recent ...
July 13, 2023 Brown dwarf stars rarely emit radio waves. Here scientists have found the coldest star yet emitting at these long wave lengths. Understanding the science of 'ultracool brown dwarfs' will ...
July 30, 2021 Astronomers have developed a new way to capture all the exquisite 'layer-cake' details of a brown dwarf's cloud structure. Because brown dwarfs are similar to super-Jupiters, this ...
Nov. 24, 2021 Researchers have discovered lithium in the oldest and coldest brown dwarf where the presence of this valuable element has been confirmed so far. This substellar object, called Reid 1B, preserves ...
