An international team of astronomers has found a new brown dwarf, one of the most massive objects of this type discovered to date. The newly detected brown dwarf, designated EPIC 212036875 b, turns out to be about 50 times more massive than Jupiter. The finding is detailed in a paper published June 13 on arXiv.org.

Another brown dwarf in the system? Study investigates properties of HD 206893
Aiming to constrain the orbit and dynamical mass of the brown dwarf in the HD 206893 system, an international team of astronomers has investigated the host star and its companion using a combination of observing techniques. Results of this observational campaign suggest the presence of another massive object in the system, most likely a brown dwarf. The findings are detailed in…
Brown Dwarf Atmospheres As The Potentially Most Detectable And Abundant Sites For Life
RockDoctor writes: Yet another provocative paper emerges onto Arxiv from Harvard’s Lingam and Loeb. Today they estimate the volume of space occupied by habitable zones (regions where liquid water is stable) in brown dwarf not-quite stars. They find that it could be orders of magnitude greater than the volume in the atmospheres of Earth-size planets. Brown dwarfs are masses of gas…
Brown dwarfs are formed in the same way as sun-like stars
Astronomers have discovered a so-called proto-disc around the proto-brown dwarf Mayrit. With this discovery, they were able to confirm for the first time that this celestial body was formed in the same way as sun-like stars. Source: https://phys.org/news/2019-05-brown-dwarfs-sun-like-stars.html…
How Did This Tiny Little Star Make Such a Big Sparkle?
Scientists spotted a superflare larger than some of the hugest solar storms on record—from what seems to be a tiny, almost Jupiter-sized star.Read more…Source: https://gizmodo.com/how-did-this-tiny-little-star-make-such-a-big-sparkle-1834120769…
