Abstract

We report that a Jupiter-mass planet, WASP-7b, transits the V = 9.5 star HD 197286 every 4.95 d. This is the brightest discovery from the WASP-South transit survey so far and is currently the brightest transiting-exoplanet system in the southern hemisphere. WASP-7b is among the densest of the known Jupiter-mass planets, suggesting that it has a massive core. The planet mass is 0.96(-0.18)(+0.12) M-Jup, the radius is 0.915(-0.040)(+0.046) R-Jup, and the density is 1.26(-0.21)(+0.25) rho(Jup) (1.67(-0.28)(+0.33) g cm(-3)).
