Scientific paper

We have recently discovered three new bright transiting explanets from the Wide Angle Search for Planets (WASP) transit survey. Here we propose to use the unique capability of Spitzer to detect the thermal emission of these planets during secondary eclipse. Together these new planets cover new regions of parameter space in terms of stellar irradation and surface gravity, and our primary goal is to test whether they exhibit stratospheric temperature inversions, as has been inferred for two other hot Jupiters. This will test the recent suggestion that there are distinct classes of hot Jupiters, with and without TiO and VO in the gas phase, and probe the atmospheric conditions at which the transitions between the two states occur.
