Planetary systems study with GALAH surveys
Pioneering photometric, astrometric, and spectroscopic surveys is helping exoplanetary scientists better constrain the fundamental properties of stars within our galaxy and the... -
Element abundances study of Cepheids
Radial abundance gradients provide sound constraints for chemo-dynamical models of galaxies. Azimuthal variations of abundance ratios are solid diagnostics to understand their... -

TMAW -- Tübingen Model Atmosphere Package WWW Interface
The Tübingen NLTE Model-Atmosphere Package (TMAP <http://astro.uni-tuebingen.de/%7ETMAP/TMAP.html>_) is a tool to calculate stellar atmospheres in spherical or... -
Grids of ATLAS9 Model Atmospheres and MOOG spectra
A grid of ATLAS9 model atmospheres has been computed, spanning Teff in 3500--8000K, log.g in 0.0--5.0, [Fe/H] in -4.0--0.0, [{alpha}/Fe] in -0.08--1.2. These parameters are... -
High-resolution synthetic stellar library
Libraries of stellar spectra are fundamental tools for the study of stellar populations and both empirical and synthetic libraries have been used for this purpose. In this... -
Population Synthesis Models at very low metallicities
Using new sets of stellar evolution models at very low metallicities (Z=10^-7^; 10^-5^) and previously published grids we examine spectral properties of the ionising continua,... -
Lithium abundances of F-K stars
An extensive profile-fitting analysis was performed for the Li(+Fe) 6707-6708{AA} feature of nearby 160 F-K dwarfs/subgiants (including 27 planet-host stars) in the Galactic... -
Atmospheric parameters of nearby F-K stars
Based on a collection of high-dispersion spectra obtained at Okayama Astrophysical Observatory, the atmospheric parameters (Teff, logg, vt, and [Fe/H]) of 160 mid-F through... -
Coronal hole parameters
Coronal holes are usually defined as dark structures seen in the extreme ultraviolet and X-ray spectrum which are generally associated with open magnetic fields. Deriving... -
CHEOPS limb and gravity-darkening coefficients
The goal of this Research Note is to provide the theoretical calculations of the limb-darkening coefficients (LDC) and gravity-darkening coefficients (GDC) for the space mission... -
Atmospheric parameters for 771 stars
A number of spectroscopic surveys have been carried out or are planned to study the origin of the Milky Way. Their exploitation requires reliable automated methods and softwares... -
Main sequence magnetic stars properties
We reconsidered the previous studies of properties of magnetic stars based on the latest data on average surface magnetic fields of 177 stars. New, corrected results have been... -
Fundamental parameters of CP stars
The paper presents the results of determination of fundamental parameters (effective temperature, surface gravity, luminosity, mass, radius, rotation velocity, and radial... -
Abundances of metal-poor stars from SkyMapper
We present chemical abundances for 21 elements (from Li to Eu) in 150 metal-poor Galactic stars spanning -4.1<[Fe/H]<-2.1. The targets were selected from the SkyMapper... -
The extended MILES library
Extragalactic astronomy and stellar astrophysics are intrinsically related. In fact, the determination of important galaxy properties such as stellar masses, star formation... -
Luminosities of 34 slowly pulsating B stars
We provide three statistical model prescriptions for the bolometric corrections appropriate for B-type stars as a function of (i) T_eff_, (ii) T_eff_ and logg, and (iii) T_eff_,... -
A bright star sample observed with SOPHIE
With the aim of probing the properties of the bright end of the Pristine survey and its effectiveness in selecting metal-poor stars, we selected a sample of bright candidate... -
Composition of eclipsing close binary systems
A spectroscopic study was carried out on the surface chemical abundances of CNO and several heavier elements in the primary and secondary components of five eclipsing close...
