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

TL;DR

This paper reports the discovery of seven new transiting hot Jupiters from the WASP-South survey, detailing their properties and analyzing the distribution of hot Jupiter orbital periods.

Contribution

It presents seven newly discovered hot Jupiters and investigates the period distribution and the 3-4 day pile-up phenomenon among known hot Jupiters.

Findings

Orbital periods range from 3.9 to 4.6 days.

Planetary masses range from 0.4 to 2.3 Jupiter masses.

Planetary densities vary from Jupiter-like to inflated.

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 to 12.5. The orbital periods are all in the range 3.9--4.6 d, the planetary masses range from 0.4--2.3 Mjup and the radii from 1.1--1.4 Mjup. In line with known hot Jupiters, the planetary densities range from Jupiter-like to inflated (rho = 0.13--1.07 rho_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".
