uvby photometry and RVs of HD 74057
We have obtained Stromgren b and y differential photometric observations of the solar-type eclipsing binary HD 74057 plus follow-up high-resolution, red wavelength spectroscopic... -
Improved properties for cool stars
We present new grids of colors and bolometric corrections for F-K stars having 4000 K {<=} Teff {<=} 6500 K, 0.0 {<=} log(g) {<=} 4.5, and -3.0 {<=} [Fe/H]... -
Rotation and binary rate among giant F stars
We have tested the hypothesis of Berthet (1991A&A...251..171B) which foresees that Am stars become giant metallic A and F stars (defined by an enhanced value of the... -
Rotational velocities of F dwarfs
table4 contains rotational velocities for 177 dwarfs with spectral types between A7 en G2. -

uvby-beta photometry of stars in SA 194
(no description available) Cone search capability for table J/A+AS/104/9/table1 (uvby-beta photometry of 594 stars in SA 194) -
Evidence of high redshift Galactic alpha-poor disc
The presence of [alpha/Fe]-[Fe/H] bi-modality in the Milky Way disc has animated the Galactic archaeology community since more than two decades. Our goal is to investigate the... -
s-process abundances in halo stars
The chemical evolution history of slow neutron-capture elements in the Milky Way is still a matter of debate, especially in the metal-poor regime ([Fe/H]<-1). Based on... -
Gaia FGK benchmark stars v3
Large spectroscopic surveys devoted to the study of the Milky Way, including Gaia, use automated pipelines to determine the atmospheric parameters of millions of stars. The Gaia... -
PySME. Spectroscopy Made Easier
The characterization of exoplanets requires reliable determination of the fundamental parameters of their host stars. Spectral fitting plays an important role in this process.... -
Classification of A-F spectral type stars
In the time of large space surveys that provide tremendous amounts of precise data, it is highly desirable to have a commonly accepted methodology and system for the... -
F-G-K stars activity indicators
Different relationships between the H{alpha} and CaII chromospheric emissions have been reported in solar-type stars. In particular, the time-series of emissions in these two... -
asPIC1.1 catalogue
The ESA PLAnetary Transits and Oscillations of stars (PLATO) mission will search for terrestrial planets in the habitable zone of solar-like stars. Because of telemetry... -
SOPHIE radial velocities of 27 F/G stars
Distinguishing classes within substellar objects and understanding their formation and evolution need larger samples of substellar companions such as exoplanets, brown dwarfs,... -
beta Cas BRITE and SMEI light curves
F type stars are characterised by several physical processes such as different pulsation mechanisms, rotation, convection, diffusion, and magnetic fields. The rapidly rotating... -
3748 FGK stars spectroscopic parameters
The Apache Point Observatory Galactic Evolution Experiment (APOGEE) has observed the H-band spectra of over 200000 stars with R~22 000. The main motivation for this work is to... -
Normalized Halpha line profiles of FGK stars
The determination of stellar effective temperature (T_eff_) in F, G, and K stars using Halpha profile fitting is a quite remarkable and powerful tool because it does not depend... -
r-process abundances in AMBRE stars
The chemical evolution of neutron capture elements in the Milky Way disc is still a matter of debate. There is a lack of statistically significant catalogues of such element... -
Gaia FGK stars: low-metallicities candidates
We have entered an era of large spectroscopic surveys in which we can measure, through automated pipelines, the atmospheric parameters and chemical abundances for large numbers... -
Overlooked wide companions of nearby F stars
We checked a sample of 545 F stars within 50pc for wide companions using existing near-infrared and optical sky surveys. Cone search capability for table J/A+A/587/A51/tablea1...
