Reddening and metallicity of NGC 6752
Accurate reddenings for Globular Clusters could be obtained by comparing the colour-temperature obtained using temperatures from reddening-free indicator (H{alpha}), with that... -
Abundances in stars with giant planets
We present Na, Mg and Al abundances in a set of 98 stars with known giant planets, and in a comparison sample of 41 "single" stars. The results show that the [X/H] abundances... -
Yields of low and intermediate mass stars
We present a set of low and intermediate mass star yields based on a modeling of the TP-AGB phase which affects the production of nitrogen and carbon. These yields are evaluated... -
Abundances in intracluster medium with XMM
XMM-Newton observations of 19 galaxy clusters are used to measure the elemental abundances and their spatial distributions in the intracluster medium. The sample mainly consists... -
Abundances in the galaxy HS 0837+4717
We present the results of high S/N long-slit spectroscopy with the Multiple Mirror (MMT) and the SAO 6-m (BTA) telescopes, optical imaging with the Wise 1-m telescope and HI... -
Oxygen abundances in the Galactic disk
Oxygen abundances for the 72 program stars. Column one gives the Hipparcos number, columns 2-6 the derived oxygen abundances for the different indicators relative to the... -
Metallicities of Slowly Pulsating B stars
We derived the stellar parameters (angular diameters, effective temperatures, metallicities) and interstellar reddenings for 20 Slowly Pulsating B (SPB) and 34 reference stars... -
Age-metallicity relation for nearby stars
Ages, Fe and Ca abundances, orbits, and populations for 1658 solar neighbourhood stars are presented. Stars are selected from Hipparcos (Cat. Catalogue. Cone search capability... -
Abundances of field BHB star candidates
New spectroscopic observations are presented for a sample of thirty-one blue horizontal branch (BHB) star candidates that are sufficiently nearby to have reliable proper... -
Evolution models for {alpha}-enhanced stars
We present four large sets of evolutionary tracks for stars with initial chemical compositions [Y=0.250, Z=0.008], [Y=0.2773, Z=0.019], [Y=0.320, Z=0.040] and [Y=0.390, Z=0.070]... -
Molecular clouds SO and CS obs. II.
We here analyse the observational SO and CS data presented in Nilsson et al. (2000A&AS..144..441N). The SO/CS integrated intensity ratio maps are presented for 19 molecular... -
Atmospheric parameters in metal-poor stars. III.
We present the results of the analysis of an extensive set of new and literature high quality data concerning Fe, C, N, O, Na, and Mg. This analysis exploited the T_eff_ scale... -
NaI in Local Bubble
We present preliminary results form a long-term program of mapping the neutral absorption characteristics of the local interstellar medium, taking advantage of Hipparcos stellar... -
Chemical spiral galaxies models
We have extended our chemical and cosmological galaxy evolution model to calculate the abundance evolution for altogether 16 different elements in spiral galaxies in a... -
Fe I in metal-poor stars
A detailed analysis of neutral iron lines in a sample of 13 metal-poor dwarfs and subgiants is carried out on the basis of high resolution spectra obtained with the ESO Coude... -
The spectrum of FG Sge in 1992
Wavelength measurements and line identifications from the 0.14A/pixel echelle spectra of FG Sge secured two weeks before the drastic dimming of the star in 1992 are presented.... -

APOGEE-2 DR17 final allStar catalog
The 2022ApJS..259...35A paper documents the seventeenth data release (DR17) from the Sloan Digital Sky Surveys; the fifth and final release from the fourth phase (SDSS-IV). DR17... -
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... -
Na, Mg, Ca abundances in K-type giants
Narrow-band photometric measures of the strengths of the Mg b, Ca triplet, and Na D lines on 312 G and K type giant stars have been analysed with a model atmosphere technique to...
