Atmospheric oscillations in white dwarfs: a new indicator of chromospheric activity.

MUSIELAK Z.E., WINGET D.E. and MONTGOMERY M.H.

Abstract (from CDS):

A new type of oscillation, the so-called atmospheric oscillations resulting from the response of stellar atmospheres to propagating acoustic waves, must be present in white dwarfs with chromospheric activity. Since these oscillations exist only in atmospheres with an outward temperature increase, they can be used as a new indicator of chromospheric activity in white dwarfs. Theoretical predictions of periods and amplitudes of the oscillations are given for selected DA and DB stars. The best candidates for detection of these oscillations are also identified.
