Intro

Our AIU-(sub-)group works on different topics of research fields. We use the latest observational techniques available at different wavelengths (radio to visual, single-dishes and interferometers, e.g., IRAM 30m, JCMT, Plateau de Bure, the ATNF telescopes, the VLA, NTT & 3.6m at La Silla, VLT).

Star and Planet Formation
We study the formation of low-mass, intermediate-mass, and high-mass stars. Especially, we are interested in the formation of high-mass stars. In contrast to low-mass star formation, the high-mass star formation habours still many open questions. Our observations address the following questions, for example, the search for massive protostellar objects or the study of massive disks around intermediate and massive stars. Moreover, our group deals with many aspects related to the formation of low-mass objects including observations of disks of brown dwarfs in the thermal and far-infrared as well as in the sub-mm regimes.

Chemistry in Molecular Cloud Cores
The study of chemistry in molecular clouds (especially Bok Globules) is another main topic of our work.

Chemistry in Protoplanetary Disks
In order to study the role of the chemistry in protoplanetary disks as well as the interplay with the evolution of the protoplanets in disks, we observe different molecular lines tracers toward these disks using world wide available radio interferometer.

Fall-back disks around neutron stars
We are searching for the dust emission of fall back disks around neutron stars.
