Ca4227 indices in early-type galaxies
We have investigated the abundance of calcium in early-type galaxies by measuring the strength of the CaI {lambda}4227 absorption line in their integrated spectra. The database... -
Abundances and velocities in globular clusters
We have compiled a sample of globular clusters with high-quality stellar abundances from the literature to compare to the chemistries of stars in the Galaxy and in dwarf... -
Metallicity indices in open clusters
We present metallicity estimates for seven open clusters based on spectrophotometric indices from moderate-resolution spectroscopy. Observations of field giants of known... -
Cepheids with periods between 3 and 6 days
We present the results of a detailed multiphase spectroscopic analysis of six classical Cepheids with pulsation periods between 3 and 6 days. For each star we have derived... -
Optical-infrared colors of CORALS QSOs
The presence of dust in quasar absorbers, such as damped Ly{alpha} (DLA) systems, may cause the background QSO to appear reddened. We investigate the extent of this potential... -
C and N abundances for M15 stars
We present an analysis of a large sample of moderate-resolution Keck Low Resolution Imaging Spectrometer spectra of subgiants and stars at the base of the red giant branch (RGB)... -
Abundances of stars within 15pc of the Sun
We present an abundance analysis for stars within 15pc of the Sun located north of -30{deg} declination. We have limited our abundance sample to absolute magnitudes brighter... -
Galactic stellar abundances
To compare the chemistries of stars in the Milky Way dwarf spheroidal (dSph) satellite galaxies with stars in the Galaxy, we have compiled a large sample of Galactic stellar... -
NStars project: the Northern Sample. I.
We have embarked on a project, under the aegis of the Nearby Stars (NStars)/Space Interferometry Mission Preparatory Science Program, to obtain spectra, spectral types, and,... -
Abundances in M3 and M13
We analyze high-resolution, high signal-to-noise ratio spectra of six red giant branch (RGB) stars in the globular cluster M3 (NGC 5272) and three in M13 (NGC 6205) that were... -
Proper motions of metal-poor stars
We present a revised catalog of 2106 Galactic stars, selected without kinematic bias and with available radial velocities, distance estimates, and metal abundances in the range... -
Low-mass stars evolutionary tracks & isochrones
These files contain a large database of stellar models that are suitable to modelling star clusters and galaxies by means of population synthesis. They are based on a large grid... -
Yields of intermediate mass stars
We present theoretical yields of H, ^4^He, ^12^C, ^13^C, ^14^N, and ^16^O for stars with initial masses between 0.8 and 8M_{sun}_ and initial metallicities Z=0.001, 0.004,... -
Molecular abundances in dense interstellar clouds
In this paper we present calculated fractional abundances in dense interstellar clouds for selected atomic and molecular species using three different homogeneous,... -
Stellar models VI.
New grids of models covering the evolution of low mass stars (0.8 to 1.7M{sun}) with metallicities Z=0.020 and 0.001 from the zero age main sequence up to the end of the early... -
Chemical evolution of the galactic disk II.
Equivalent widths of programme stars used in Paper I (1993A&A...275..101E, see catalog ) from observations at ESO and McDonald observatories are compared. -
Transitions of SI in visible and infra-red

Chemical abundances in LINERs from MaNGA. I
The chemical enrichment in low-ionization nuclear emission-line regions (LINERs) is still an issue with spatial resolution spectroscopic data due to the lack of studies and the... -
Bulk metallicity of giant planets around M stars
Determination of the bulk metallicity of giant exoplanets is essential in order to constrain their formation and evolution pathways and to compare them to the Solar System.... -
SPLUS DR4 VAC - Predicted Parameters
The APOGEE, GALAH, and LAMOST spectroscopic surveys have substantially contributed to our understanding of the Milky Way by providing a wide range of stellar parameters and...
