Ages, Metallicities, Galactic Orbit of F stars
Absolute magnitudes, metallicities, effective temperatures, surface gravities, distances, and tangential velocities are calculated for 5498 F stars with homogeneous data on uvby... -
Geneva-Copenhagen Survey of Solar neighbourhood III
Ages, chemical compositions, velocity vectors, and Galactic orbits for stars in the solar neighbourhood are fundamental test data for models of Galactic evolution. The... -
Geneva-Copenhagen Survey of Solar neighbourhood
(no description available) Cone search capability for table V/117A/newcat (Main catalogue recalibrated data (2007)) -
KOI planets and KIC stars from Kepler DR25
In order to gain a better understanding of planet formation and evolution, it is important to examine the statistics of exoplanets in the Galactic context. By combining... -
Solar-type stars Halpha line
Excess chromospheric emissions within deep photospheric lines are effective proxies of stellar magnetism for FGK stars. This emission decays with stellar age and is a potential... -
Study of Kepler's FGKM stars
While stellar rotation periods P_rot_ may be measured from broad-band photometry, the photometric modulation becomes harder to detect for slower rotators, which could bias... -
FGK targets GaiaDR2/TESS matches
We present stellar parameter estimates for 939457 southern FGK stars that are candidate targets for the Transiting Exoplanet Survey Satellite (TESS) mission. Using a data-driven... -
Cerro Armazones spectroscopy of F dwarfs
We present a spectroscopic survey of a sample of F stars that have not yet been searched for planets. The observations of 187 stars obtained with the Bochum Echelle... -
Atmospheric param. of 169 FGKM stars
The asteroseismic and planetary studies, like all research related to stars, need precise and accurate stellar atmospheric parameters as input. We aim at deriving the effective... -
Radial metallicity gradient from RAVE DR3
We investigate radial metallicity gradients for a sample of dwarf stars from the RAdial Velocity Experiment (RAVE) Data Release 3 (DR3, Cat. III/265). We select a total of... -
Elemental abundances for 176 stars
We have performed an abundance analysis for F- and G- dwarfs of the Galactic thick-disc component. A sample of 176 nearby (d<=150pc) thick-disc candidate stars was chosen... -
[X/Fe] of Galactic disc F and G dwarfs
Photospheric abundances are presented for 27 elements from carbon to europium in 181 F and G dwarfs from a differential local thermodynamic equilibrium (LTE) analysis of... -

Surface rotation & activity for Kepler stars. II.
Dark magnetic spots crossing the stellar disk lead to quasiperiodic brightness variations, which allow us to constrain stellar surface rotation and photometric activity. The... -
FGK stars magnetic activity in LAMOST-Kepler field
Monitoring chromospheric and photospheric indexes of magnetic activity can provide valuable information, especially the interaction between different parts of the atmosphere and... -
Radial velocities of overluminous F stars
We have conducted a radial-velocity survey of bright (V<9), overluminous, F stars within 80pc. Of the total of 118 stars selected, the radial velocities of 77 have been... -
Photometric monitoring from 2008-2018 of 11 PPNe
We have carried out a new photometric V,R_C_ study of 12 protoplanetary nebulae, objects in the short-lived transition between the asymptotic giant branch and planetary nebula... -
Spitzer/IRAC fluxes of the HD 166191 system
We report on five years of 3-5{mu}m photometry measurements obtained by warm Spitzer to track the dust debris emission in the terrestrial zone of HD 166191 in combination with... -
V-band phot. & spectra of the EB BT Vul
We report extensive differential V-band photometry and high-resolution spectroscopy for the 1.14d, detached, double-lined eclipsing binary BT Vul (F0+F7). Our radial-velocity... -
Radial velocities of Milky Way inner halo stars
We measure the three components of velocity dispersion, {sigma}R, {sigma}{theta}, {sigma}{phi}, for stars within 6<R<30kpc of the Milky Way using a new radial velocity...
