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... -
CaII H and K filter photometry II.
A catalog of 1990 stars on the Caby system is presented. The sample includes stars covering an extensive range in spectral type, luminosity class, and metallicity, as well as... -
Metal-poor MS stars UBV photometry
From analysis of a photometrically selected sample of 175 metal-poor field stars with main sequence gravities (hereafter BMPs) and UBV colors blueward of the most metal-poor... -
Halo red giants reddening
Updated uvby observations for a larger sample of metal-deficient red giants are presented and combined with a select sample of data from the literature transformed to a common... -
Spectroscopy of hot stars in galactic halo
The paper presents spectroscopy for 769 hot stars from the HK objective-prism/interference-filter survey of Beers et al. (1985), 193 of which have also available broadband UBV... -
Stars of very low metal abundance
Spectroscopic observations for 1044 stars located primarily in the southern Galactic hemisphere are reported; the stars were chosen from a list of candidate metal-deficient... -
uvby-beta photometry of metal-poor stars
A second catalogue of uvby-beta photometry for 553 high-velocity stars is given; nearly all of these stars come from the Lowell Proper Motion Survey. These data have been taken... -
Chemical composition of halo and disk stars
Table 3. Atmospheric parameters, space velocities, distances, masses and ages of the program stars. Table 4. Atomic line data including wavelength, excitation energy of the... -
HD 133029 & HD 192913 elemental abundances
Fine analyses of the silicon stars HD 133029 and HD 192913 are presented using ATLAS9 model atmospheres whose predictions fit the optical region spectrophotometry and H{gamma}... -
Mg2 indices for early-type galaxies
We present 210 new measurements of the central absorption line-strength Mg_2_ index for 87 early-type galaxies drawn from the Prugniel & Simien (1996, Cat. ) sample. 28... -
Abundances of HR 4487, 14 Hyd and 3 Cen A
Ussing CASLEO echelle spectrograms, elemental abundances are derived for the sharp-lined non-magnetic CP stars HR 4487, 14 Hya and 3 Cen A. The first two stars are members of... -
uvby-beta photometry of metal-poor stars. VIII.
A catalogue of uvby-{beta} photometry for 87 of the turn-off and subgiant stars from the HK survey of Beers et al. (1992AJ....103.1987B, BPSII) is given. Most of these stars... -

Pristine-Gaia follow-up of EMP stars
We present the first spectroscopic follow-up of bright (G<15) and distant (up to 35kpc) very and extremely metal-poor (V/EMP, [Fe/H]<-2.5) red giant branch stars from the... -
Metal-poor stars NLTE abundances of Eu
As a key to chemical evolutionary studies, the distribution of elements in galactic provides a wealth of information to understand the individual star formation histories of... -
Earliest phases of CNO enrichment in galaxies
The recent detection of super-solar carbon-to-oxygen and nitrogen-to-oxygen abundance ratios in a bunch of metal-poor galaxies at high redshift by the James Webb Space Telescope... -
S-PLUS Ultra-Short Survey DR1
This paper presents the first public data release of the S-PLUS Ultra-Short Survey (USS), a photometric survey with short exposure times, cove ring approximately 9300deg^2^ of... -
Pristine Inner Galaxy Survey. X.
We aim to constrain the chemo-dynamical properties of the Sagittarius (Sgr) dwarf galaxy using carbon abundances. At low metallicities in particular, these properties reveal the... -
Phosphorus-rich stars. II.
The atmospheres of phosphorus-rich (P-rich) stars have been shown to contain between 10 and 100 times more P than our Sun. Given its crucial role as an essential element for... -
Metal-poor accreted star cand. abund.
The Milky Way is a mosaic of stars from different origins. In particular, metal-poor accreted star candidates offer a unique opportunity to better understand the accretion...
