Query: WASP-52b, WASP-58b, WASP-59b, and WASP-60b: four new transiting close-in
  giant planets   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 7.9
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, 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 (+17/-9) degrees,
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.
