WASP 180Ab : Doppler tomography of an hot Jupiter orbiting the primary star in a visual binary
... We proceeded to obtain radial velocity (RV) measurements with the Euler/CORALIE (Queloz et al. 2001) spectrograph. WASP- 180A is a fast rotating F star with broad lines giving large RV errors, so the CORALIE RVs ruled ...
