[en] stars: individual: WASP-7 HD 197286 ; planetary systems
[en] 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[SUP]+0.12[/SUP] [SUB]--0.18[/SUB] M [SUB]Jup[/SUB], the radius is 0.915[SUP]+0.046[/SUP] [SUB]--0.040[/SUB] R [SUB]Jup[/SUB], and the density is 1.26[SUP]+0.25[/SUP] [SUB]--0.21[/SUB] rho[SUB]Jup[/SUB] (1.67[SUP]+0.33[/SUP] [SUB]--0.28[/SUB] g cm[SUP]--3[/SUP]).
