WASP-22 b: A TRANSITING “HOT JUPITER” PLANET IN A HIERARCHICAL TRIPLE SYSTEM
We report the discovery of a transiting planet orbiting the star TYC 6446-326-1. The star, WASP-22, is a moderately bright (V=12.0) solar-type star (Teff = 6000 +/- 100 K, [Fe/H] = -0.05 +/- 0.08). The lightcurve of the star obtained with the WASP-South instrument shows periodic transit-like features with a …
