  • Cool L- and T-type objects were discovered first as companions to stars in 1988 and 1995, respectively. A certain example of the even cooler Y-type spectral class (Teff < 500 K) has not been seen. Recent infrared-imaging observations of stars and brown dwarfs indicate that substellar companions with large semi-major axes and with masses less than the brown dwarf/giant planet dividing line (∼13.5 MJ) are rare. Theoretical considerations of the Jeans mass fragmentation of molecular clouds are… CONTINUE READING
