Dear group,
A couple of weeks ago we had the announcement surrounding the discovery of the twelveth exoplanet by the HAT-P-Net exoplanet hunting team and involving the third find and example to-date of a "Hot Saturn".
This particular find involves a star which is somewhat dim at magnitude 12.84 (pretransit) and which dims to 12.865 during transit. In spite of many false starts due to very dim sporadic clouds which almost made me call it in, I managed to capture a very beautiful light
curve over the course of four hours.
The exoplanet HAT-P-12b in the constellation of Canis Venatici completely orbits its parent star in only 77 hours and requires 140 minutes to transit it as viewed from Earth. Aside from being the least dense of any massive gas giant exoplanet discovered so far, it is even less dense than Saturn itself.
For the resulting light-curve from last night based on 4 hours total data, please see http://www.perseus.gr/Astro-Photometry-HAT-P-12-20090513.htm .
Anthony.
