This dissertation presents a study of the circumstellar gas and dust emission and their relation to the mass-loss in evolved stars. Considering the physical process of heating and cooling of the dust,...
Dust driven mass loss from carbon stars as function of stellar parameters - II. Effects of grain size on wind properties
AGB and post-AGB – Stars: atmospheres – Stars: carbon – Stars: circumstellar matter – Stars: evolution – Stars: mass loss –2 Hydrodynamics – Radiative transfer

In this paper we explore grain size effects on wind properties of carbon stars, using a generalized description of radiative cross sections valid for particles of arbitrary sizes. The purpose of the s...
Mass Loss, Destruction and Detection of Sun-grazing and -impacting Cometary Nuclei
comet sun impact sun-grazing radiation collisions
font style='font-size:12px;'>
2011/9/30
Incoming sun-grazing comets almost never re-emerge, but no final destruction event has ever been observed, nor sun-impactor destruction theory developed. We seek analytic models of comet nucleus destr...

The mass-loss rates of red supergiants the de Jager prescription
font style='font-size:12px;'>
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

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
font style='font-size:12px;'>
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

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

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
