DOIAbstract
International audienceWe report the discovery of two transiting hot Jupiters, WASP-65b (M-pl = 1.55 + 0.16 M-j; R-pl = 1.11 +/- 0.06 R-j), and WASP-75b (M-pl = 1.07 +/- 0.05 M-j; R-pl = 1.27 +/- 0.05 R-j). They orbit their host star every similar to 2.311, and similar to 2.484 days, respectively. The planet host WASP-65 is a G6 star (T-eff = 5600 K, [Fe/H] = -0.07 +/- 0.07, age greater than or similar to 8 Gyr); WASP-75 is an F9 star (T-eff = 6100 K, [Fe/H] = 0.07 +/- 0.09, age similar to 3 Gyr). WASP-65b is one of the densest known exoplanets in the mass range 0.1 and 2.0 M-j (p(pl) = 1.13 +/- 0.08 rho(j)), 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 ...
