Sub-mm images of SSTB213 J041757.75+274105.5
We observed the proto brown dwarf candidate SSTB213 J041757 with the Submillimeter Array to search for CO molecular outflow emission from the source. Our CO maps do not show any... -
Stellar models with rotation. 0.8<M<120, Z=0.002
We study the impact of a subsolar metallicity on various properties of non-rotating and rotating stars, such as surface velocities and abundances, lifetimes, evolutionary... -
Models for rotating stars
B-type stars are known to rotate at various velocities, including very fast rotators near the critical velocity as the Be stars. In this paper, we provide stellar models... -
Stellar models with rotation. 0.8<M<120, Z=0.014
Many topical astrophysical research areas, such as the properties of planet host stars, the nature of the progenitors of different types of supernovae and gamma ray bursts, and... -
Modelling of AGB stars in the LMC
Asymptotic giant branch (AGB) stars are major contributors to both the chemical enrichment of the interstellar medium and the integrated light of galaxies. Despite its... -
Grid of solar-metallicity wind models
Knowing how the mass loss of carbon-rich AGB stars depends on stellar parameters is crucial for stellar evolution modelling, as well as for the understanding of when and how... -
Modelling of Magellanic Cloud C/O stars
Mass loss is one of the fundamental properties of Asymptotic Giant Branch (AGB) stars, and through the enrichment of the interstellar medium, AGB stars are key players in the... -
Mass-loss rates of galactic AGB stars
We are using the 2002 data-release from the Japanese space experiment IRTS to investigate the spatial distribution of galactic mass-losing (>2x10^-8_M_{sun}/yr) AGB stars and... -
Galactic mass-losing AGB stars
AGB mass-losing sources are easy to identify and to characterize in the near-infrared range (1-5{mu}m). We make use of the near-infrared data acquired by the Japanese space... -
Investigation of mass loss mechanism of LPVs
In order to investigate the relations between the mass loss from pulsating red giants and quantities which can be obtained from observations, we have explored the behavior of... -
Stellar evolution. II. Post-AGB
We present a set of evolutionary tracks for central stars of planetary nebulae in the range from 0.53 to 0.94M_{sun}. These models are based on extensive stellar evolution... -

Near IR Photometry of a Sample of IRAS Point Sources
The results are given for the 516 sources that we have observed from La Silla (452 in the southern hemisphere, plus 64 in the range 0 to 20deg). For each source, the IRAS name...
