I am Professor for Astronomy at the Hamburger Sternwarte (observatory), which is part of the Department of Physics of the University of Hamburg.

My main area of research is the modeling of stellar and planetary atmospheres using computer simulations with our PHOENIX code. This is a large scale supercomputing application, my group regularily uses large parallel supercomputers that can be found in the top 10 of the world's machines. A short CV of me is available (PDF) and I also have a list of publications available (PDF, infrequently updated, please use ADS for up-to-date information!). I also participate in the DFG Graduiertenkolleg 1351 "Extrasolar Planets and their Host Stars" and the SFB 676 (project C5). The observatory is also part of a successful Hamburg Landesexzellenzinitiative proposal, details about this project can be found here. My group has always opportunities for Bachelor/Master/Diploma theses in the field of theoretical and computational astrophysics, please contact me for more information.

Vorlesungsinfos

Im WiSe 2009 halte ich folgende Veranstaltungen: Einführung in die Astronomie I (BSc), Theorie und Praxis von PHOENIX (Spezialvorlesung, StwB), das Astronomische Praktikum, und das Proseminar über Astrophysik.

Im SoSe 2010 halte ich folgende Veranstaltungen: Einführung in die Astronomie II (BSc), Theorie und Praxis von PHOENIX (Spezialvorlesung, StwB), das Astronomische Praktikum (keine Anmeldung erforderlich, bitte zum ersten Termin zur Vorbesprechung, Gruppeneinteilung etc kommen, es sollte genügend Plätze geben). Die Astro II eignet sich auch für Studenten die nicht im BSc Physik Studiengang der UHH sind (insbesondere Studenten der TUHH sind herzlich willkommen).

Astronomy program information

I am the official astronomy advisor for students interested in astronomy. Please feel free to contact me any time with questions regarding astronomy at the University of Hamburg by e-mail, phone or in person (please call ahead to make an appointment to make sure I'll be around!). You can also check out the web pages of the observatory for a FAQ list. This link gives some information for students who plan to take astronomy as "Nebenfach" in the "Vordiplom" or "Hauptstudium (Physik Diplom)".

My main research interests are (not necessarily in this order):

• 3D radiative transfer algorithms and their implementation.
• continue the development & verification of PHOENIX/3D.
• The atmospheres and spectra of novae, M dwarfs & giants, Brown Dwarfs, L/T dwarfs, T Tauri's, SNe, basically everything that radiates.
• Irradiation of planets and secondaries of CVs
• Analyses of Nova, M/L/T dwarf & giant, Brown Dwarf, T Tauri, and SN spectra.
• The detailed physics of nova spectra, in particular line blanketing and NLTE effects.
• Numerical methods for NLTE and radiative transfer calculations.
• Line formation, blending and blanketing in (relativistically) expanding atmospheres.
• Radiative transfer in relativistically expanding, spherical atmospheres.
• Detailed NLTE calculations for extremely large model atoms.
• Effective numerical methods to treat 100's of millions spectral lines individually with detailed profiles.
• Molecular line opacities.
• Line broadening in very cool stars.
• Finishing the next versions of the M/L/T-O dwarf and nova model grids.
• Models for Stellar Winds
• Keeping PHOENIX/1D and PHOENIX/3D alive and happy (currently at version 16).
