Backyard Star or Brown DwarfKristin Leutwyler
WISE 2220−3628 is a brown dwarf of spectral type Y, and hence one of the coolest star-like objects known. WISE 2220−3628是一顆光譜型為Y的棕矮星,有一顆類似恆星的天體很靠近它。 LASER-wikipedia2 Kapteyn's Star Groombridge 1830 Mu Cassiopeiae 2MASS J05325346+8246465, a possible halo...

A brown dwarf displays its aurora in this artist's concept. Chuck Carter and Gregg Hallinan/Caltech When is something too small to be a star, yet too massive to be a planet? When it's a brown dwarf, otherwise known as a "failed star." But if you think the failed star moniker is...

A brown dwarf star is a sub-stellar object whose mass ranges between that of gas giant planets and small stars. Its mass is too low for it to fuse hydrogen, as main-sequence stars like our Sun do. Brown dwarfs can be thought of as a kind of 'missing link' between planets and stars...

We have studied the photometric variability of very young brown dwarfs and very low mass stars (masses well below 0.2 M) in the Cha I star-forming region. We have determined photometric periods in the Gunn i and R bands for the three M6.5-M7 type brown dwarf candidates Cha Hα 2, Cha...
