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$^+0.12$ $_-0.18$ M $_Jup$, the radius is 0.915$^+0.046$ $_-0.040$ R $_Jup$, and the density is 1.26$^+0.25$ $_-0.21$ $$_Jup$ (1.67$^+0.33$ $_-0.28$ g cm$^-3$).
