Part 2 . Pulsation , Mass Loss ,
The most direct evidence for the pulsation mode of Mira and SR variables comes from the linear diameters derived from individual parallaxes and angular diameters, together with the observed periods. The data now available strongly suggest that most, if not all, Miras and SRs pulsate in the same mode. If comparison is made with conventional models, this mode is the first overtone. Uncertainties ...
متن کاملCepheid Mass-loss and the Pulsation – Evolutionary Mass Discrepancy
I investigate the discrepancy between the evolution and pulsation masses for Cepheid variables. A number of recent works have proposed that non-canonical mass-loss can account for the mass discrepancy. This mass-loss would be such that a 5M⊙ star loses approximately 20% of its mass by arriving at the Cepheid instability strip; a 14M⊙ star, none. Such findings would pose a serious challenge to o...
متن کاملThe coupling between pulsation and mass loss in massive stars
To what extent can pulsational instabilities resolve the mass-loss problem of massive stars? How important is pulsation in structuring and modulating the winds of these stars? What role does pulsation play in redistributing angular momentum in massive stars? Although I cannot offer answers to these questions, I hope at the very least to explain how they come to be asked.
متن کاملThe Transition to Axisymmetrical Mass Loss
Any model for the formation of elliptical planetary nebulae (PNs) should account for the positive correlation between the mass loss rate and the degree of departure from sphericity of the AGB progenitor's wind. I propose that this correlation results from dust formation above magnetic cool spots. The model deals with elliptical PNs, but not with bipolar PNs. The basic assumption is that a weak ...
متن کاملOn the Enhancement of Mass Loss in Cepheids Due to Radial Pulsation
An analytical derivation is presented for computing mass–loss rates of Cepheids by using the method of Castor et al. (1975) modified to include a term for momentum input from pulsation and shocks generated in the atmosphere. Using this derivation, mass–loss rates of Cepheids are determined as a function of stellar parameters. When applied to a set of known Cepheids, the calculated mass–loss rat...
