Non-adiabatic linear pulsation models for low-mass helium stars.
JEFFERY C.S. and SAIO H.
Abstract (from CDS):
The implications of these results for individual low-mass helium stars are discussed. It is concluded that Z-bump driven pulsations (radial and/or non-radial) may be excited in some helium-rich subdwarf B stars, representing a possible major extension to the class of variable stars represented by the prototype V652 Her.
