We 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 7.9Â days , masses between 0.46 and 0.94 M _ { \mathrm { Jup } } , and radii between 0.73 and 1.49 R _ { \mathrm { 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 , whereas WASP-59b is likely to have a large , dense core .
WASP-60 shows shallow transits .
In the case of WASP-52 we also detected the Rossiter-McLaughlin anomaly via time-resolved spectroscopy of a transit .
We measured the sky-projected obliquity \lambda = 24 ^ { \circ } ^ { +17 } _ { -9 } , indicating that WASP-52b orbits in the same direction as its host star is rotating and that this prograde orbit is slightly misaligned with the stellar equator .
These four new planetary systems increase our statistics on hot jupiters , and provide new targets for follow-up studies .
