Rotational frequency splitting in Sun-like stars
Asteroseismology offers the prospect of constraining differential rotation in Sun-like stars. Here we have identified six high signal-to-noise main-sequence Sun-like stars in... -
Rotation periods of 12000 Kepler stars
We aim to measure the starspot rotation periods of active stars in the Kepler field as a function of spectral type and to extend reliable rotation measurements from F-, G-, and... -
Chromospheric activity of field stars
Compilation of S-index measurements available in the literature cross-correlated with the CDS catalog. The S-index is a measure of the strength of the chromospheric emission in... -
61 main-sequence and subgiant oscillations
Solar-like oscillations have been observed by Kepler and CoRoT in several solar-type stars, thereby providing a way to probe the stars using asteroseismology We provide the mode... -
SDSS WD main-sequence binaries. XII.
The complexity of the common-envelope phase and of magnetic stellar wind braking currently limits our understanding of close binary evolution. Because of their intrinsically... -
Abundances in solar analogs
We derive the abundance of 19 elements in a sample of 64 stars with fundamental parameters very similar to solar, which minimizes the impact of systematic errors in our... -
Chemical abundances of 32 mildly metal-poor stars
We present photospheric abundances of the O, Na, Mg, Al, Si, Ca, Sc, Ti, V, Cr, Mn, Ni, and Ba elements for 32 mildly metal-poor stars with [Fe/H]~-0.7. High resolution and high... -
Galactic disk stars abundances and velocities
We have performed the detailed analysis of 174 high-resolution spectra of FGK dwarfs obtained with the ELODIE echelle spectrograph at the Observatoire de Haute-Provence.... -
Abundances of late G/K dwarfs in solar neighborhood
In this investigation, a technique developed by Spinrad and Taylor for obtaining metal abundances of late-type stars, and used by them in an earlier investigation of evolved... -
Vyssotsky's Catalogues 1950.0
This catalog includes the results of a complete survey of the McCormick objective prism plates for M dwarf stars. catalog.dat includes identifications, magnitudes, proper... -
Dwarf K and M stars of small proper motion
(no description available) Cone search capability for table III/123B/catalog (The original catalogue of 2201 stars) Cone search capability for table III/123B/stkm1 (The catalog... -
Two long-period transiting exoplanets
Long-period transiting planets provide the opportunity to better understand the formation and evolution of planetary systems. Their atmospheric properties remain largely... -
Proxima telluric-corrected ESPRESSO RV
Ground-based high-resolution spectrographs are key instruments for several astrophysical domains, such as exoplanet studies. Unfortunately, the observed spectra are contaminated... -
AD Leo RV and stellar activity indices
A challenge with radial-velocity (RV) data is disentangling the origin of signals either due to a planetary companion or to stellar activity. Obtaining data over a large time...
