Hot Jupiters, although abundant among Sun-like stars, seem to get rarer with decreasing stellar mass. The goal of the Pan-Planets transit survey was the detection of such planets and a statistical characterization of their frequency. Here, we announce the discovery and validation of two planets found in that survey, Wendelstein-1b and Wendelstein-2b, two short-period hot Jupiters that orbit late K host stars. We validated them both by the traditional method of radial velocity measurements with the HIRES and HPF instruments and then by their Transit Colour Signature (TraCS). With this, we demonstrate that multi-band photometry is an effective way of confirming transiting exoplanets.
