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... -
Planetary nebulae abundances
Long slit spectrophotometry of 13 bipolar planetary nebulae has been used to study their physical and chemical properties. In each nebula, one to seven different spatial regions... -
Spectroscopy of Alpha Cen
This table presents the results of a spectroscopic analysis (differentially to the Sun) of the two components of the binary system Alpha Centauri. This analysis has been carried... -
Structure and evolution of low-mass stars
Properties of Very Low mass stars for different initial metallicity [M/H] and Helium mass fraction: mass (in solar mass), age (in Gyrs) effective temperature (in K), log of... -
Abundances in globular clusters
Tables 5, 6, and 7 present details of the derived abundances for the stars observed in the globular clusters M2, M13, and M56, respectively. Table 9 gives the measured... -
Chemical composition of six K supergiants in the SMC
A sample of six SMC cool stars (K supergiants) are analysed by high resolution spectroscopy in order to investigate their chemical content, which should reflect that of the... -
Chemical composition of the s-Cepheids
On the base of photographic, Reticon and CCD spectra analysis we have derived the abundances for 8 s-Cepheids and V1162 Aql (before classified as s-Cepheid). The following... -
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 catalogue includes chemical abundances determinations (from Li to Eu) and atmospheric parameters (Teff, logg, microturbulent velocity) obtained from re-analyses of 1108... -
The PASTEL catalogue
PASTEL is a bibliographical catalogue compiling determinations of stellar atmospheric parameters. It provides (Teff, logg, [Fe/H]) determinations obtained from detailed analyses... -
Atmospheric parameters in metal-poor stars. I
We present atmospheric parameters for about 300 stars of different chemical composition, whose spectra will be used to study the galactic enrichment of Fe and light elements.... -
Molecules in O- and C-rich envelopes
Observations of 10 microwave transitions of the molecules SiO, HCN, HNC, SiS, HC_3_N, CS, SO, and ^13^CO are presented in a total sample of 47 evolved stars. The studied sources... -
Abundance gradients from disk PNs
A new determination of the radial abundance gradients of O/H, Ne/H, S/H, and Ar/H is made for disk planetary nebulae, (PN), that is, those objects of Peimbert types I, II, and... -
Chemical abundances of PNe
All modern determinations of chemical abundances of He/H, O/H, C/H, N/H and Ne/H in 277 galactic Planetary Nebulae have been used to update our knowledge of the chemical... -
Abundances of late G/K dwarfs in solar neighborhood
