I am interested in the physics and chemistry of substellar atmospheres, that are atmospheres of Brown Dwarfs and Giant Gas Planets. These objects have the particularity of forming dust clouds in their atmosphere much as we know it from our Earth, except that the chemistry is very different. This different chemistry makes it quit a challenge since the one-to-one translation of terrestrial cloud and atmosphere models does not work. Also turbulence plays a role, a topic with which already Heisenberg struggled during his PhD. Here is an introduction to my work: Everyone's Understanding of Turbulent Dust Formation.
The stationary version of the model for oxygen-rich, heterogeneous dust formation is now part of a radiative transfer atmosphere code (PHOENIX, Hamburg), and that version of PHOENIX was named DRIFT-PHOENIX.
DRIFT-PHOENIX substellar atmosphere data for: I've also worked on winds of AGB stars which caused my interest for low-metallicity problems.
As one result of this are here
