New paper on the disappearing disk of TYC 8241 2652 1

TYC 8241 2652 1 is a young star that showed a strong mid-infrared (mid-IR, 8-25 mu) excess in all observations before 2008 consistent with a dusty disk. Between 2008 and 2010 the mid-IR luminosity of this system dropped dramatically by at least a factor of 30 suggesting a loss of dust mass of an order of magnitude or more. We aim to constrain possible models including removal of disk material by stellar activity processes, the presence of a binary companion,…

Exoplanets conference in Bonn

This week I am in Bonn, Germany, to give an invited talk entitled “Interactions between exoplanets and their host stars” at the conference Exoplanets – Bridging the gap between theory and observations. The conference takes place at the beautiful historical Physikzentrum in Bad Honnef. Lots of interesting talks and posters, from planet definitions (and how we should change them) to upcoming observational missions and planet formation theory. Plenty of time for discussion with all participants!
