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...

File table1.dat contains the log of the spectroscopic observations of the stars in the EXPORT sample taken with the Isaac Newton Telescope during the 1998...

Many problems in contemporary astrophysics—from understanding the formation of black holes to untangling the chemical evolution of galaxies—rely on knowledge...

In this first paper, we measured the strength of the CN and CH band indices, which correlate with the N and C abundances, and we investigated the anti...

Various natural effects gradually alter the surfaces of asteroids exposed to the space environment. These processes are collectively known as space weathering...

With the goal of confirming the metallicity ``excess'' observed in stars with planetary mass companions, we have conducted a high-precision spectroscopic study...

Increasing space activities, especially in low-Earth orbits (LEO), lead to more orbital debris and night-sky pollution. Spectroscopic analysis of light...

The dynamics of the merger between a high- and a low-elliptical galaxy was studied to understand how kinematically peculiar cores in elliptical galaxies might...

Stellar flares are characterized by sudden enhancement of electromagnetic radiation from the atmospheres of stars. Compared to their solar counterparts, our...
