Effects of Mass Loss on the Late Stages of Stellar Evolution

open access: yesPhysics Reports, 1987
Advances in the infrared and radio observational techniques in the last decade have led to a revolution in our understanding of the late stages of stellar evolution. Intermediate (1–8 M⊙) mass stars are found to be undergoing rapid mass loss in the form of a stellar wind during the asymptotic-giant-branch after the exhaustion of helium burning in the ...

Late stages of stellar evolution

open access: yesEAS Publications Series, 2008
Mass loss is an important ingredient in the evolution of stars, in particular during late stages of stellar evolution, when mass loss often is the dominant factor. The far-IR window enables to probe the outflows of evolved stars at different depths, providing direct access to the driving mechanisms. The spatial and spectral resolution of Herschel offer

Late-Stage Stellar Evolution: Impact on Planets

International Journal of Astrobiology, 2009
AbstractAmong the many cosmic cataclysms that can influence life, we focus on the impact that the most critical phases of the late-stage stellar evolution may have on planets. To give an example, the red giant expansion of the Sun will probably engulf the inner planets, including perhaps the Earth.

V 439 CYG as a Late Phase of Stellar Evolution

Astrophysics and Space Science, 1997
V 439 Cyg lies in the nearby (950 pc), heavily reddened open cluster Berkeley 87. This cluster is probably part of the starforming region ON2, where many compact HII regions, strong OH masers, CO and ammonia molecular clouds and high energy sources have been detected (Manchanda et al. 1996, and references therein).

Late Stages of Stellar Evolution

Space Science Reviews, 2005
A large fraction of ISO observing time was used to study the late stages of stellar evolution. Many molecular and solid state features, including crystalline silicates and the rotational lines of water vapour, were detected for the first time in the spectra of (post-)Asymptotic Giant Branch (AGB) stars. Their analysis has greatly improved our knowledge

Diffusion in late stages of stellar evolution

Annales de Physique, 1991
The abundances of the chemical elements observed at the surface of white dwarfs are the result of diffusion in the external regions of these stars. It is described how diffusion determines the abundances of such elements as carbon, that are now being observed in the far UV.
