dc.description.abstractWe report the detection of a brown dwarf candidate orbiting the metal-rich K dwarf HD 91669, based on radial-velocity data from the McDonald Observatory Planet Search. HD 91669b is a substellar object in an eccentric orbit (e = 0.45) at a separation of 1.2 AU. The minimum mass of 30.6M(Jup) places this object firmly within the brown dwarf desert for inclinations i greater than or similar to 23 degrees. This is the second rare close-in brown dwarf candidate discovered by the McDonald planet search program.en_US
