Identification of pulsating A- and F-type stars in binary systems

Correlation between chemical peculiarities and pulsation behavior

Insights into the interaction of stellar phenomena in the instability strip

Abstract

The region in the HR-diagram where the main sequence intersects the classical instability strip hosts A- and F-type stars exhibiting a rich variety of physical phenomena, such as pulsations on various time scales and chemical peculiarities. We aim to investigate the occurrence of these phenomena among suspected binary systems in this region of the HR-diagram and their mutual interactions.
