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 ...
Jan. 7, 2021 —Using high-precision brightness measurements from NASA's TESS space telescope, astronomers found that the nearby brown dwarf Luhman 16B's atmosphere is dominated by high-speed, global winds ...
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 ...
Jan. 14, 2021 —Astronomers have curated the most complete list of nearby brown dwarfs to date thanks to discoveries made by thousands of volunteers participating in the Backyard Worlds citizen science project. The ...
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 ...
Nov. 9, 2020 —New research has led to the first direct discovery of a cold brown dwarf from its radio wavelength emission. Along with paving the way for future brown dwarf discoveries, this result is an important ...
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 ...
Feb. 9, 2021 —Astronomers have found that some dwarf galaxies may today appear to be dark-matter free even though they formed as galaxies dominated by dark matter in the ...
