We report on the discovery and confirmation of Kepler-7b, a transiting planet with unusually low density. The mass is less than half that of Jupiter, M(P) = 0.43 M(J), but the radius is 50% larger, R(P) = 1.48 R(J). The ...

Discovery Of A Low-Mass Companion To The Solar-Type Star Tyc 2534-698-1

Kane, Steven R.; Mahadevan, Suvrath; Cochran, William D.; Street, Rachel A.; Sivarani, Thirupathi; Henry, Gregory W.; Williamson, Michael H. (2009-02)

Brown dwarfs and low-mass stellar companions are interesting objects to study since they occupy the mass region between deuterium and hydrogen burning. We report here the serendipitous discovery of a low-mass companion in ...
