Improved parameters for the transiting hot Jupiters WASP-4b and WASP-5b
Improved parameters for the transiting hot Jupiters WASP-4b and WASP-5b
The gaseous giant planets WASP-4b and WASP-5b are transiting 12-magnitude solar-type stars in the Southern hemisphere. The aim of the present work is to refine the parameters of these systems using high cadence VLT/FORS2 <i>z<i/>-band transit photometry and high-resolution VLT/UVES spectroscopy. For WASP-4, the new estimates for the planet radius …
