Abstract

We present the discovery of two new hot Jupiters identified from the WASP survey, WASP-186b and WASP-187b (TOI-1494.01 and TOI-1493.01). Their planetary nature was established from SOPHIE spectroscopic observations, and additional photometry was obtained from TESS. Stellar parameters for the host stars are derived from spectral line, IRFM, and isochrone placement analyses. These parameters are combined with the photometric and radial velocity data in an MCMC method to determine the planetary properties. WASP-186b is a massive Jupiter (4.22±0.18 MJ, 1.11 ±0.03 RJ) orbiting a mid-F star on a 5.03 day eccentric (e=0.327±0.008) orbit. WASP-187b is a low density (0.80 ±0.09 MJ, 1.64 ±0.05RJ) planet in a 5.15 day circular orbit around a slightly evolved early F-type star.
