Physics of Mass Loss in Massive Stars [PDF]
Proceedings of the International Astronomical Union, 2014 AbstractWe review potential mass-loss mechanisms in the various evolutionary stages of massive stars, from the well-known line-driven winds of O-stars and BA-supergiants to the less-understood winds of Red Supergiants. We discuss optically thick winds from Wolf-Rayet stars and Very Massive Stars, and the hypothesis of porosity-moderated, continuum ...

Slowing down atomic diffusion in subdwarf B stars: mass loss or turbulence? [PDF]
, 2011 Subdwarf B (sdB) stars show chemical peculiarities that cannot be explained by diffusion theory alone. Both mass loss and turbulence have been invoked to slow down atomic diffusion in order to match observed abundances.

Hot stars mass-loss studied with Spectro-Polarimetric INterferometry (SPIN) [PDF]
, 2003 We present a prospective work undertaken on Spectro-Polarimetric INterferometry (SPIN). Our theoretical studies suggest that SPIN is a powerful tool for studying the mass loss from early type stars where strong Thomson scattering is present.

The Evolution of Massive Helium Stars, Including Mass Loss [PDF]
Astrophysical Journal, 2019 The evolution of helium stars with initial masses in the range 1.6–120 is studied, including the effects of mass loss by winds. These stars are assumed to form in binary systems when their expanding hydrogenic envelopes are promptly lost just after ...

Theory and Diagnostics of Hot Star Mass Loss [PDF]
Annual Review of Astronomy and Astrophysics, 2021 Massive stars have strong stellar winds that direct their evolution through the upper Hertzsprung–Russell diagram and determine the black hole mass function.

Mass Loss from Cool Stars [PDF]
Annual Review of Astronomy and Astrophysics, 1981 AbstractRecently obtained spectroscopic observations indicating mass loss in cool stars are reviewed with analogies to the solar atmosphere. Spectral diagnostics of mass loss are discussed with new theoretical calculations of chromospheric line profiles.

Mass Loss and Evolution of Massive Stars [PDF]
International Astronomical Union Colloquium, 1981 In the past few years both growing observational evidence and theoretical understanding have shown that mass loss by stellar wind is a common occurrence in the evolutionary history of many types of star. Recent reviews on the subject may be found in Conti (1978), Cassinelli (1979), Conti and Mc Cray (1980), Hutchings (1980a), de Loore (1979, 1980) and ...

Evolution of Binary Stars with Mass Loss [PDF]
Symposium - International Astronomical Union, 1979 Three situations involving mass loss from binary systems are discussed. (1) Non-conservative mass exchange in semi-detached binaries. No quantitative estimate of this mechanism is possible at present. (2) Common envelope binaries. There are both theoretical and observational indications that this phase of evolution happens to many systems, even to some

PARSEC V2.0: Stellar tracks and isochrones of low and intermediate mass stars with rotation [PDF]
Astronomy & Astrophysics, 2022 We present a new comprehensive collection of stellar evolutionary tracks and isochrones for rotating low- and intermediate-mass stars assembled with the updated version of PARSEC V2.0. This version includes our recent calibration of the extra mixing from

Evolution of single stars with mass loss [PDF]
Symposium - International Astronomical Union, 1979 A.Mass loss has been observed by means of UV, optical, IR and radio observations.B.There exists also indirect evidence that stars lose matter during their evolution.
