Michel Mayor used astrometric data provided by Hipparcos in conjunction with the radial velocity method to investigate ten candidates for them.

S Ori 47 has the lowest mass of any known one of these and they release substantial amounts of infrared radiation. Known to fuse deuterium on a small scale, their name was coined by Jill Tarter and Gliese 229B was the first one to be confirmed. The maximum mass of one of these is believed to be approximately 84 times the mass of Jupiter, or the largest mass that is insufficient for normal hydrogen fusion. For 10 points, name this dimmest and least massive star, sometimes referred to as a "failed star."
