WASP-44b, WASP-45b and WASP-46b: three short-period, transiting extrasolar planets

The orbital parameters and the radius of the planet were estimated by best fitting the phase folded light curve with 34 successive transits.. Doppler measurements with the

To choose the best model, we compared the discrete MM4 model, continuous MM2, MM3 and MM4 corresponding to fits with
