Abstract

Polarimetry of planets and planetary systems provide unique information on physics and chemistry of planetary atmospheres. We have built a new instrument, GREGOR Planet Polarimeter (GPP), which includes fast polarimetric modulation, high-rate readout CCD, and adaptive optics. It operates at the solar telescope GREGOR on Tenerife, Canary Islands, and it benefits from the possibility to calibrate the entire optical train after the secondary mirror. Here we present the instrument design, performance tests, and first scientific data. This research is supported by the ERC Advanced Grant HotMol.
