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 ρJup (1.67+0.33 –0.28 g cm^–3).
