Abstract

We report the discovery of three new transiting extrasolar planets orbiting moderately bright (V = 11.1, 11.7, and 12.4) F stars. The planets HAT-P-39b through HAT-P-41b have periods of P = 3.5439 days, 4.4572 days, and 2.6940 days, masses of 0.60 M-J, 0.62 M-J, and 0.80 M-J, and radii of 1.57 R-J, 1.73 R-J, and 1.68 R-J, respectively. They orbit stars with masses of 1.40 M-circle dot, 1.51 M-circle dot, and 1.51 M-circle dot, respectively. The three planets are members of an emerging population of highly inflated Jupiters with 0.4 M-J < M < 1.5 M-J and R > 1.5 R-J.
