We have determined Li, C, N, O, Na, and Fe abundances, and ^12^C/^13^C isotopic ratios for a sample of 62 field metal-poor stars in the metallicity range -2<=[Fe/H]<=-1....

The results of calibration of the surface brightness, bolometric flux and effective temperature scales are presented for 537 dwarfs and giants selected as standards for the...

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...

We list in Table 1 the observed stars together with some of their characteristics. Distances, expansion velocities, mass loss rates, and spectral types are taken from the...

We have used the IRAM 30 m-telescope together with the Max Planck Institute for Radio Astronomy (MPIfR) bolometer to survey nearly 270 stars of different types for 250GHz...

The relation between the CaII H and K line-tore flux density and rotation period is studied for a sample of 313 cool stars of luminosity classes ranging from II-III to V, and...

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...

Based on the analysis of high-resolution spectra with a high signal-to-noise ratio, we have determined the abundances of the alpha-elements O, Si, Ca and Ti, the iron peak...

We present precise effective temperatures (Teff) of 215 FGK giants determined using the method of line-depth ratios. For each star, we have measured the line depths and...

A 'complete' sample of 174 M giants classified in the mid-1980s by Blanco (1986AJ.....91..290B) and later than subtype M0 in the NGC 6522 Baade's Window clear field has been...

We present FCAPT differential Johnson BV and Cousins RI photometry and radial velocities of the S-type AGB stars RS Cnc, ST Her, OP Her and HR Peg. We performed multiperiodic...

The results of a comparative analysis of the kinematics, ages, and elemental abundances for 17 red giants in the Hercules moving group are presented. Model atmospheres are used...

We have determined the atmospheric abundances of Y, Ba, La, Ce, Pr, Nd, and Eu for a sample of 171 giants selected as clump giants with metallicities [Fe/H] between 0.7 and...

The spectral lines of high and low excitation potentials respond differently to the change in effective temperature (Teff). Therefore, the ratio of their depths (or equivalent...

We analyze the Na, Mg, Al, and Si abundances in the atmospheres of more than 40 stars, including red giants of different spectral subgroups (normal red giants, mild and...

Surface-averaged longitudinal magnetic field components have been measured for 15 late-type giants with an accuracy of several Gauss. Cone search capability for table...

The energy distributions for 27 giants and supergiants of the M spectral type are presented in the region of 3200-7600{AA} with the step of 50{AA}. The observations were made in...

We present a collection of 65,981 Mira-type variable stars found in the Optical Gravitational Lensing Experiment (OGLE) project database. Two-thirds of our sample (40,356...

The Kepler mission has provided exquisite data to perform an ensemble asteroseismic analysis on evolved stars. In this work we systematically characterize solar-like...

We investigate the multiple stellar populations in one of the peculiar globular clusters (GCs), M22, using new ground-based wide-field Ca by and Hubble Space Telescope...
