Hot Subdwarfs: Magnetic, Oscillatory and Other Physical Properties

Hot subdwarf stars (hot sds) are blue subluminous objects. Only a few determinations are available to date regarding the study of such aspects as rotation, microturbulent velocities or the magnetic nature of these objects. Over 26 sdBs are known to date to be multiperiodic rapid oscillators. This pr...

Zusammenfassung:	Hot subdwarf stars (hot sds) are blue subluminous objects. Only a few determinations are available to date regarding the study of such aspects as rotation, microturbulent velocities or the magnetic nature of these objects. Over 26 sdBs are known to date to be multiperiodic rapid oscillators. This project presents preliminary results of new observations and models of a sample of pulsating and non-pulsating hot sds, including considerations on mass loss and eventual magnetic properties.
