... present the discovery of four new transiting hot jupiters, detected mainly from SuperWASP-North and SOPHIE observations. These new planets, WASP-52b, WASP-58b, WASP-59b, and WASP-60b, have orbital periods ranging from 1.7 to 7.9 days, masses between 0.46 and 0.94 M_Jup, and radii between 0.73 and 1.49 R_Jup. Their G1 to K5 dwarf host stars have V magnitudes in the range 11.7-13.0. The depths of the transits are between 0.6 and 2.7%, depending on the target. With their large radii, WASP-52b and 58b are new cases of low-density, inflated planets...

WASP-52b is a hot jupiter which is less than half the mass of Jupiter, but with a significantly larger radius. It is thus a new example of an inflated hot jupiter. Together with the small radius of its K2V host star, it makes the planetary transits particularly deep at 2.7 %.
