Thermal response of stellar envelopes during nonradial pulsations
Abstract
The response of spherical stellar envelopes in hydrostatic and thermal balance to nonradial thermal distributions is outlined. Because of the nature of the initial model, the governing equations yield an operator that is almost identical to the radial case. The use of propagation velocities to estimate the nonadiabatic effects in a pulsation is demonstrated.
