Abstract:
We report the discovery of three extrasolar planets that transit their
moderately bright (mV=12-13) host stars. WASP-44b is a 0.89-MJup
planet in a 2.42-day orbit around a G8V star. WASP-45b is a
1.03-MJup planet which passes in front of the limb of its K2V host
star every 3.13-days. Weak CaII H&K emission seen in the spectra of
WASP-45 suggests that the star is chromospherically active. WASP-46b
is a 2.10-MJup planet in a 1.43-day orbit around a G6V star.
Rotational modulation of the light curves of WASP-46 and weak CaII H&K
emission in its spectra show the star to be photospherically and
chromospherically active.
