Stellar mass loss and atmospheric instability

International Astronomical Union Colloquium, 1988
AbstractA review is given of rate of mass-loss values in the upper part of the Hertzsprung-Russell diagram. Near the luminosity limit of stellar existance = −10−4 M⊙ yr−1. Episodical mass loss in bright variable super- and hypergiants does not significantly increase this value. For Wolf-Rayet stars the rate of mass loss is larger by a factor 140 than

IRAS and cool stellar mass loss

2008
We show that the band strength of the 9.7μm silicate dust feature is well correlated with the CO and OH-maser line strengths, and so provides a reliable measure of mass-loss rates for cool, luminous, Oxygen-rich stars. Correlations are presented between mass-loss rates and various physical properties of the M-Supergiants in the IRAS LRS Catalogue.

Effects of pulsation and mass loss on stellar evolution

Nature, 1984
There is much evidence that many post-main sequence stars are losing mass, that the integrated mass loss is sufficient to affect their evolution and that epochs of substantial mass loss are normal for almost all stars. However, neither the precise timing, nor the mechanisms, nor the full consequences of this mass loss are yet well understood.

Stellar Winds and Mass Loss in A-Type Supergiants

Astrophysics and Space Science, 1998
We examine the relationship between the surface escape velocities and wind terminal velocities of A-type supergiants according to the radiation-driven wind theory.

Stellar Adiabatic Mass Loss in Binary Stars

AIP Conference Proceedings, 2010
Stellar adiabatic mass loss model show us the approximate responses of the donor stars suffering rapid mass loss. According to the radius response and the change of total energy during adiabatic mass loss, we present our results on the criteria of dynamical mass transfer instability and the limits on common envelope evolution.
