Abstract:
Ground-based simultaneous multiband transit observations allow an
accurate system parameter determination and may lead to the detection
and characterization of additional bodies via the transit timing
variations (TTVs) method.
We aim to (i) characterize the heavily bloated WASP-4b hot Jupiter and
its star by measuring system parameters and the dependence of the
planetary radius as a function of four (Sloan g', r', i', z')
wavelengths and (ii) search for TTVs.
Description:
GROND optical (Sloan g', r', i' and z') light curves of WASP-4,
