HAT-P-39b--HAT-P-41b: Three Highly Inflated Transiting Hot Jupiters

Abstract

We report the discovery of three new transiting extrasolar planets orbiting moderately bright (V=11.1 to 12.4) F stars. The planets have periods of P = 2.6940 d to 4.4572 d, masses of 0.60 MJ to 0.80 MJ, and radii of 1.57 RJ to 1.73 RJ. They orbit stars with masses between 1.40 Msun and 1.51 Msun. The three planets are members of an emerging population of highly inflated Jupiters with 0.4 MJ < M < 1.5 MJ and R > 1.5 RJ.
