We present the results of detailed spectroscopic abundance analyses for 18 elements in 31 nearby stars with planets (SWPs). The resulting abundances are combined with other...

The connection between age, rotation and chemical abundance of magnetic Ap stars is poorly understood. Using open clusters, we are able to study samples of stars that are both...

We present measurements of ages, metallicities and [alpha/Fe] ratios for 16 globular clusters (GCs) in NGC 147, 185 and 205 and of the central regions of the diffuse galaxy...

Lithium abundances are presented for a total of 451 F-G dwarfs. The aim of this survey of Lithium abundance is to document the astration of Li as a function of stellar mass,...

Lithium abundances are presented for 81 main-sequence stars with effective temperatures of about 5800-6700K. Cone search capability for table J/MNRAS/253/610/table1 (Equivalent...

The high resolution spectra of hydrogen-deficient binary {upsilon} Sgr are analyzed. The atmospheric parameters are T_eff_= 12300+/-200K, logg=2.5+/-0.5 and {xi}t=5-15km/s...

For the catalog, we compiled the abundances of 28 chemical elements: alpha-elements (O, Mg, Si, Ca, Ti), carbon, iron-peak elements(Sc, V, Cr, Mn, Fe, Co, Ni, Cu, Zn), slow and...

Data of our compiled catalog containing the positions, velocities, and metallicities of 415 RR Lyrae variable stars and the relative abundances [el/Fe] of 12 elements for 101 RR...

A catalog compiling the parameters of 346 open clusters, including their metallicities, positions, ages, and velocities has been composed. The elements of the Galactic orbits...

We have determined abundances of copper, zinc, sodium, and aluminium in the atmospheres of 172 F, G, and K dwarf stars (-1.0<[Fe/H]<0.3) belonging to the Galaxy's thin and...

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...

Based on high-resolution spectra we revealed variability of the optical spectrum of the cool star identified with the IR source IRAS 20508+2011. Over the five years of our...

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...

The results of a spectroscopic analysis of 15 stars that are photometric analogues of the Sun are reported. The effective temperatures and surface gravities in the stellar...

Based on the set of high accuracy observational data on the components of SB2 eclipsing binaries and the grid of stellar models calculated by Geneva group for the wide range of...

We compile, from the existing literature, the largest sample to date (842 data points) of hydrogen column density measurements, N(HI), of the gas in the interstellar medium. We...

A catalog is presented of some 1200 Galactic objects which have radial velocities and abundances [Fe/H]<=-0.6. These data have been analyzed to yield information on the...

The measurements of masses and luminosities of massive stars play an important role in understanding the formation and evolution of their host galaxies. In this work, we present...

Using ion measurements from Ultra-Low-Energy Isotope Spectrometer observations on board Advanced Composition Explorer and Solar Isotope Spectrometer observations on board the...
