Abstract
‘Thermo-mechanical’ oscillations of a radiating spherically-symmetric shell containing a fermion gas (i.e., oscillation where only mechanical, thermodynamical, and eventually radiation phenomena are taken into account) are studied. With a reasonable choice of the three relevant parameters all other observational data are similar to the ones of X-ray bursters and recurrent novae.
Therefore, thermo-mechanical oscillations could play an important role in the oscillation spectrum of these astronomical objects.
