Abstract (from CDS):

We report the discovery of two transiting hot Jupiters, WASP-65b (Mpl=1.55±0.16MJ; Rpl=1.11±0.06RJ), and WASP-75b (Mpl=1.07±0.05MJ; Rpl=1.27±0.05RJ). They orbit their host star every ∼2.311, and ∼2.484-days, respectively. The planet host WASP-65 is a G6 star (Teff=5600K, [Fe/H]=-0.07±0.07, age >8Gyr); WASP-75 is an F9 star (Teff=6100K, [Fe/H]=0.07±0.09, age ∼3Gyr). WASP-65b is one of the densest known exoplanets in the mass range 0.1 and 2.0MJpl=1.13±0.08ρJ), a mass range where a large fraction of planets are found to be inflated with respect to theoretical planet models. WASP-65b is one of only a handful of planets with masses of ∼1.5MJ, a mass regime surprisingly underrepresented among the currently known hot Jupiters. The radius of WASP-75b is slightly inflated (≲10%) as compared to theoretical planet models with no core, and has a density similar to that of Saturn (ρpl=0.52±0.06ρJ).
