Previous studies showed evidence of a dearth of close-in exoplanets around fast rotators, which can be explained by the combined action of intense tidal and magnetic...

The detection of stellar variability often relies on the measurement of selected activity indicators, such as coronal emission lines and nonthermal emissions. On the flip side,...

The study of blue straggler stars (BSS) provides insights into the mechanisms of stellar mass exchange during binary stellar evolution and the complex gravitational interactions...

We present stellar parameters and abundances of 13 elements for 18 very metal-poor (VMP; [Fe/H]{<}-2.0) stars, selected as extremely metal-poor (EMP; [Fe/H]{<}-3.0)...

The precise determination of stellar atmospheric parameters (effective temperature T_eff_, surface gravity log g, and metallicity [Fe/H]) serves as a cornerstone for Galactic...

Binary stars containing a white dwarf and a main-sequence star, WDMS binaries, can be used to study a wide range of aspects of stellar astrophysics. We build a magnitude-limited...

Reliable stellar atmospheric parameters are essential for probing stellar structure and evolution, and for stellar population studies. However, various deviations appear in...

The search for extra-terrestrial life is one of the ultimate goals for future exoplanet-seeking missions while one of the major challenges these missions face is the possible...

The search and interpretation of non-radial pulsations from Be star light curves observed with the CoRoT satellite requires to obtain high quality stellar astrophysical...

We use high-quality K2 light curves for hundreds of stars in the Pleiades to better understand the angular momentum evolution and magnetic dynamos of young low-mass stars. The...

We present an initial overview of the targets to be found in the 1-square-degree SEP region that was observed repeatedly by Gaia ever since its commissioning. In our...

We present the abundances of magnesium (Mg) and silicon (Si) for 314 dwarf stars with spectral types in the interval K7.0-M5.5 (Teff range 4200-3050K) observed with the CARMENES...

The ultra-faint dwarf (UFD) galaxy Reticulum 2 (Ret 2) was recently discovered in images obtained by the Dark Energy Survey (Diehl et al. 2014SPIE.9149E..0VD). We have observed...

In its three years of operation, the Sloan Digital Sky Survey Apache Point Observatory Galactic Evolution Experiment (APOGEE-1) observed >14000 stars with enough epochs over...

PASTEL is a bibliographical catalogue compiling determinations of stellar atmospheric parameters. It provides (Teff, logg, [Fe/H]) determinations obtained from detailed analyses...

Gravito-inertial asteroseismology saw its birth thanks to high-precision CoRoT and Kepler space photometric light curves. So far, it gave rise to the internal rotation frequency...

Gaia Data Release 3 (Gaia DR3) will be released on 13 June 2022. The Gaia DR3 catalogue builds upon the Early Data Release 3 (released on 3 December 2020) and combines, for the...

The catalogue includes chemical abundances determinations (from Li to Eu) and atmospheric parameters (Teff, logg, microturbulent velocity) obtained from re-analyses of 1108...

The catalogue includes [Fe/H] determinations and atmospheric parameters (Teff, logg ) obtained from high resolution spectroscopic observations and detailed analyses, most of...

The catalogue presented here is a compilation of published atmospheric parameters (Teff, logg, [Fe/H]) obtained from high resolution, high signal-to-noise spectroscopic...
