We report the discovery of a transiting planet orbiting the star TYC 2-1155-1 .
The star , WASP-32 , is a moderately bright ( V=11.3 ) solar-type star ( \mbox { $T _ { eff } $ } = 6100 \pm 100 K , [ Fe/H ] = -0.13 \pm 0.10 ) .
The lightcurve of the star obtained with the WASP-South and WASP-North instruments shows periodic transit-like features with a depth of about 1 % and a duration of 0.10 d every 2.72 days .
The presence of a transit-like feature in the lightcurve is confirmed using z-band photometry obtained with Faulkes Telescope North .
High resolution spectroscopy obtained with the CORALIE spectrograph confirms the presence of a planetary mass companion .
From a combined analysis of the spectroscopic and photometric data , assuming that the star is a typical main-sequence star , we estimate that the planet has a mass M _ { p } of 3.60 \pm 0.07 M _ { Jup } and a radius R _ { p } = 1.19 \pm 0.06 R _ { Jup } .
WASP-32 is one of a small group of “ hot Jupiters ” with masses > 3 M _ { Jup } .
We find that some stars with hot Jupiter companions and with masses M _ { \star } \approx 1.2 M _ { \sun } , including WASP-32 , are depleted in lithium , but that the majority of these stars have similar lithium abundances to field stars .
