Abstract

We report the discovery of HAT-P-25b, a transiting extrasolar planet orbiting the V = 13.19 G5 dwarf star GSC 1788-01237, with a period P = 3.652836 0.000019 days, transit epoch T_c = 2455176.85173 0.00047 (BJD - barycentric Julian dates throughout the paper are calculated from Coordinated Universal Time, UTC), and transit duration 0.1174 0.0017days. The host star has a mass of 1.01 0.03 M, radius of 0.96^+0.05 _{- 0.04} R, effective temperature 5500 80K, and metallicity [Fe/H] = +0.31 0.08. The planetary companion has a mass of 0.567 0.022M _J and radius of 1.190^+0.081 _{- 0.056}R _J yielding a mean density of 0.42 0.07 g cm^-3.
