Abstract

We announce the discovery of the transiting hot Jupiter WASP-157b in a 3.95-d orbit around a V = 12.9 G2 mainsequence star. This moderately inflated planet has a Saturn-like density, with a mass of 0.57 ± 0.10 M_Jup and a radius of 1.06 ± 0.05 R_Jup. We do not detect any rotational or phase curve modulations, nor the secondary eclipse, with conservative semi-amplitude upper limits of 250 and 20 ppm, respectively.
