Seven transiting hot Jupiters from WASP-South, Euler and TRAPPIST: WASP-47b, WASP-55b, WASP-61b, WASP-62b, WASP-63b, WASP-66b and WASP-67b

Abstract

We present seven new transiting hot Jupiters from the WASP-South survey. The planets are all typical hot Jupiters orbiting stars from F4 to K0 with magnitudes of V = 10.3-12.5. The orbital periods are all in the range of 3.9-4.6 d, the planetary masses range from 0.4 to 2.3 M Jup and the radii from 1.1 to 1.4 R Jup . In line with known hot Jupiters, the planetary densities range from Jupiter-like to inflated ( = 0.13-1.07 Jup ). We use the increasing numbers of known hot Jupiters to investigate the distribution of their orbital periods and the 3-4 d 'pile-up'.
