Non-LTE Ga abundance in HgMn stars
We present, for the first time, the Non-LTE gallium equivalent widths for the most prominent gallium transitions as identified in real spectra and in (hot) mercury-manganese... -
Non-linear limb-darkening law for LTE models
A new non-linear limb-darkening law, based on the Least-Squares Method (LSM), is presented. This law is able to describe the intensity distribution much more accurately than any... -
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... -
Rotating models of A and F stars
Magnitude differences between rotating and non-rotating copartners for a grid of models with solar metallicity are tabulated here. The results are expressed in terms of the... -
Limb-darkening coefficients for ubvyUBVRIJHK
Linear and non-linear limb-darkening coefficients for the photometric bands u v b y U B V R I J H K are computed for very low effective temperatures stars. The atmosphere models... -
O-M stars model atmospheres
Broad band colors and bolometric corrections in the Johnson-Cousins-Glass system (Bessell, 1990PASP..102.1181B; Bessell & Brett, 1988PASP..100.1134B) have been computed from... -
Chromospheric models of dwarf M stars
Tables 4 and 5 give the atmospheric parameters for our models of dM stars Gl 588 and Gl 628. The columns give the column mass in g/cm^-2^, the electron temperature in K, the... -
Miras temperatures, distances & magnitudes
Effective temperatures are determined for a sample of 165 oxygen-rich Miras using indices related to molecular band strength of titanium oxide and vanadium oxide. Using a... -

Theoretical spectral energy distributions (SEDs) from expanding NLTE model atmospheres for hot stars. -
O/Fe abundances of 15 RR Lyrae
In order to study how the conventional spectroscopic method based on the equivalent widths of the Fe I and Fe II lines effectively applies to determining the atmospheric... -
Solar-like activity of low-mass stars
An analysis of data on chromospheric activity obtained in the framework of exoplanet-search programs is presented. Observations of 1334 stars showing that the chromospheric... -
Sodium abundances in stellar atmospheres
The non-LTE sodium abundances of 100 dwarf, giant and subgiant stars with metallicities -3<[Fe/H]<0.3 are determined using high-dispersion spectra with high... -
Late type giants and supergiants in X-Ray
Results are presented of an extensive X-ray survey of 380 giant and supergiant stars of spectral types from F to M, carried out with the Einstein Observatory. It was found that... -
CaII HK emission in rapidly rotating stars
We present measurements of chromospheric CaII H&K activity for 481 solar-like stars. To determine the activity we used the Mount Wilson method and a newly developed method... -
UV Flux distributions of gamma Dor stars
It seems that the recently identified class of pulsating stars, the gamma Dor type-variables, includes objects with different metal abundances and a large percentage of... -
The VLT-FLAMES Survey of Massive Stars
An analysis is presented of VLT-FLAMES spectroscopy for three Galactic clusters, NGC 3293, NGC 4755 and NGC 6611. Non-LTE model atmosphere calculations have been used to... -
Parameters of cool companions of sdB stars
We present the analysis of a high-resolution, high-quality sample of optical spectra for 76 subdwarf B (sdB) stars from the ESO Supernova Ia Progenitor Survey (SPY, Napiwotzki...
