We have measured Mg_2_, Fe5270 and Fe5335 spectrophotometric indices (LICK system) in the bulge of 89 galaxies, mostly spirals from the Heraudeau sample. The indices are reduced...

Narrowband images of 51 symbiotic stars were obtained at the ESO and ORM observatories to search for resolved optical nebulae. Ionized nebulae much larger than previously known...

We have analyzed the optical spectra of 67 symbiotic stars and objects suspected of being symbiotic, and found 18 new symbiotic systems. This is the largest homogeneous set of...

We present a database of 908 stellar spectra of 709 stars in the wavelength range 410 to 680 nm obtained with the ELODIE spectrograph. The archive provides a large coverage of...

We present the second data release (DR2) of the XXL Survey, contextually with the appearance of a second A&A special issue dedicated to XXL. This intermediate release...

The catalog contains the ultraviolet flux measurements at wavelengths of 130-420nm, obtained with an objective-prism telescope during the three manned Skylab missions (Skylab 2,...

The atlas contains the fluxes (2 angstroms/step) of 229 low-dispersion stellar spectra collected by the International Ultraviolet Explorer (IUE) satellite, compiled for the...

The catalog is a subset comprising data for 60 O- and B-type stars observed by the Copernicus satellite. For each star a FITS file was created of the observed spectrum. Each...

This catalogue contains observations carried out by the S2/68 Ultraviolet Sky Survey Telescope (UVSST) aboard the ESRO Satellite TD-1, which measured the absolute ultraviolet...

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...

ELODIE.3.1 is an updated release of the library published in Prugniel & Soubiran (2001A&A...369.1048P, Cat. III/218; and 2004 version, in astro-ph/0409214). The library...

Silva and Cornell have compiled a new digital optical stellar spectra library, consisting of intensities at 5A intervals between 3510A and 8930A for 72 different spectral types....

The atlas represents a collection of spectra in the wavelength range 2.00 to 2.45 micrometers having a resolution of approximately 0.02 micrometers. The sample of 73 stars...

The catalog contains spectrophotometry at approximately 10-Angstrom resolution for 173 southern Wolf-Rayet stars. All observations were made at the Cerro Tololo Inter-American...

The catalog contains a homogeneous set of optical spectrophotometric observations (3300-7300 angstroms) at moderate resolution (about 10 angstroms) of 86 Wolf-Rayet carbon and...

This catalog contains a collection of K-band spectra for 26 stars with near-solar abundances, ranging in spectral class from F8 to M7 and in luminosity from dwarfs to...

Abundance parameters have been derived from scanner observations of 229 stars. Observations were made with the Wampler photoelectric spectrum scanner (Wampler, 1966) on Lick...

A and F stars can be used as probes of outer Galactic disk kinematics: here we extend the work of Harris et al. (2018, Cat. J/MNRAS/475/1680) by crossmatching their A/F sample...

Previous studies of the rotation law in the outer Galactic disc have mainly used gas tracers or clump giants. Here, we explore A and F stars as alternatives: these provide a...

Globular clusters produce many exotic stars due to a much higher frequency of dynamical interactions in their dense stellar environments. Some of these objects were observed...
