In recent years, gravitational waves (GWs) have been detected from various sources, including black hole (BH) and neutron star (NS) mergers, posing new...

In this article I review surface abundances in stars which host planetary systems. Recent spectroscopic studies of stars with and without planetary systems have...

We have developed TGMETalpha in order to determine T_{eff}, log g, [Fe/H] and [alpha /Fe] for large samples of FGK stars observed at various spectral...

New spectroscopic observations have been obtained for a sample of H II regions located toward the galactic anticentre region. The sample includes H II regions...

Spectroscopic data of low-mass X-ray binaries (LMXB) can provide valuable information on supernova properties. In these systems the companion star is probably...

The results of detailed, high-spatial-resolution spectroscopy for a sample of eleven nebulae surrounding Wolf-Rayet stars: S308, NGC 2359, NGC 3199, Anon (MR 26...

The file EW.dat lists the equivalent widths (EW) of all the spectral lines. Columns 1, 2, and 3 list the name of the stars, wavelength and EWs of the lines. The...

The file table1.dat lists the parameters used to assign the Galactic population to which each star belongs. Columns 2, 3, and 4 list the U,V and W velocities...

The high-velocity black hole in the low mass X-ray binary XTE J1118+480 could be the remnant of an massive star formed in the early stages of the evolution of...
