Stellar winds of first stars in the Universe (GA205/07/0031)

hot. Present hot stars have stellar winds accelerated due to the light absorption stars in the Universe had stellar winds. We will test the influenceof rotation on the stellar winds of first stars. We plan to study ste...

Atmospheres and circumstellar environment of magnetic hot stars (GA16-01116S)

Traditionally, the stellar mass is regarded as the main parameter that determines the stellar evolution. However, now it is clear that also other parameters, particularly magnetic field, influence many aspects of the stellar
