Mass-loss rate predictions for hot stars (GA205/08/0003)

Massive hot stars constitute an important part of our Galaxy and many other galaxies. Consequently, a detailed knowledge of their evolution and of their influence on the circumstellar environment is necessary for our unders...

The origin of dark neutral gas structures around galaxies (GA19-18647S)

, typical of disc galaxies. One interpretation is that the line width indicates rotation, implying a high dark matter content. If so such objects would be galaxies without stars structures detected in the Arecibo Galaxy...

Exploring the Hot Universe and Understanding Cosmic Feedback (GX21-13491X)

The Lambda Cold Dark Matter model has been shown to be remarkably successful matter. However, the physical processes associated with the evolution of the baryonic matter are complex and still poorly understood. In the cours...

Circumstellar environment of evolved hot stars (GAP209/11/1198)

from a circumstellar source. Interestingly, stars from all three groups show besides their infrared excess due to hot circumstellar dust, strong line emission disk. We thus aim at investigating the circumstellar conditions...

Molecules in the environments of evolved massive stars (GA17-02337S)

Recent analysis of the circumstellar material of B[e] supergiants (B[e]SGs) revealed the surprising result that these stars are surrounded by multiple Keplerian rings of gas, molecules, and dust. So far, only few ring tracers exist, and a mo...

Structure and evolution of stellar ejecta (GA20-00150S)

Optical and infrared imaging revealed that massive stars are often surrounded by large-scale nebula, witnesses of mass ejection phases. The massive B[e] stars display intense emission, characteristic for dense circumstellar nebulae. However ...
