About us

Spectroscopy is a branch of science concerned with the study of spectra produced when matter interacts with or emits electromagnetic radiation field.  On Earth, spectroscopy has a wide variety of applications: from medicine to geophysics.

Our Research Group applies the methods of spectroscopy to study stars — the fundamental units of the Universe. 

We observe stars on very large telescopes and use the measured spectra to study the structure and properties of stellar atmospheres, the low-density outer gaseous shells, which display a variety of physical phenomena, just like the Earth's atmosphere. 

From stellar spectra we can also determine the abundances of chemical elements, the data that ultimately tell us about the formation and evolution of stars, nucleosynthesis of elements in nature, formation of planetary systems, history and evolution of  galaxies.

Our group is supported by grants from the Max Planck Society and from DFG (Sonderforschungsbereich 881).
