A brown dwarf candidate has been identified orbiting around a young star by Rebolo et al. (p. 1309; see the news story by Hellemans) through optical and infrared studies. Its distance (about 300 Earth-sun distances) and low mass (about 25 Jupiter masses) relative to the star suggest that the binary system formed by fragmentation of a collapsing molecular cloud. The lower limit on the estimated age of the star (about 100 million years) suggests that substellar mass companions can form on relatively short time scales.
