The mass-loss rates of red supergiants and the de Jager prescription
The mass-loss rates of red supergiants the de Jager prescription
2011/1/11
Mass loss of red supergiants (RSG) is important for the evolution of massive stars, but is not fully explained. Several empirical prescriptions have been proposed, trying to express the mass-loss rate...
Fuel Efficient Galaxies: Sustaining Star Formation with Stellar Mass Loss
cosmology theory – galaxies evolution – galaxies formation – stars formation – methods
2010/11/11
We examine the importance of secular stellar mass loss for fueling ongoing star formation in disk galaxies during the late stages of their evolution. For a galaxy of a given stellar mass, we calculate...
A possible solution to the mass-loss problem in M-type AGB stars
mass-loss problem M-type AGB stars
2010/11/12
Mass loss is a fundamental, observationally well-established feature of AGB stars but many aspects of this process still remain to be understood. To date,self-consistent dynamical models of dust-drive...
The mass-loss rates and molecular abundances of S-type AGB stars
mass-loss rates molecular abundances of S-type AGB stars
2010/11/12
The S-type stars are believed to have a C/O-ratio close to unity (within a few percent). They are considered to represent an intermediate evolutionary stage as AGB stars evolve from oxygen-rich M-type...
Abundance anomalies in pre-main-sequence stars: Stellar evolution models with mass loss
Diffusion — stars chemically peculiar — stars mass–loss — stars pre–main-sequence — stars evolution — stars
2010/11/12
Aims. The effects of atomic diffusion on internal and surface abundances of A and F pre–main-sequence stars with mass loss are studied in order to determine at what age the effects materialize, as wel...
Mass loss rates inferred from mid-IR color excesses of LMC and SMC O stars
Solar and Stellar Astrophysics (astro-ph.SR) Galaxy Astrophysics (astro-ph.GA)
2011/1/6
We use a combination of VJHK and Spitzer} [3.6], [5.8] and [8.0] photometry, to determine IR excesses in a sample of LMC and SMC O stars.
Observing and modeling the dynamic atmosphere of the low mass-loss C-star R Sculptoris at high angular resolution
Solar and Stellar Astrophysics (astro-ph.SR)
2010/12/27
We study the circumstellar environment of the carbon-rich star R Scl using the near- and mid-infrared high spatial resolution observations from the ESO-VLTI instruments VINCI and MIDI. These observati...
Be stars are thought to be fast rotating stars surrounded by an equatorial disc. The formation, structure and evolution of the disc are still not well understood. In the frame of single star models, i...
