PublicationWhy are Massive O-rich AGB Stars in our Galaxy not S-stars?
We present the main results derived from a chemical analysis carried out on a large sample of galactic O-rich AGB stars using high resolution optical...

PublicationWhy we need to measure turbulent magnetic fields in HII regions
We have measured the emission line profiles in Hα from populations of HII regions in nearby spiral galaxies, and extracted their non-thermal line widths. These...

PublicationWide binaries among halo subdwarfs.
The authors present results of a search for wide companions to halo subdwarfs of known metallicity. They have taken CCD I-band frames in order to detect faint...

PublicationWide Field Observations of the Ursa Minor dSph Galaxy
Ursa Minor (UMi) is one of the closest satellites of the Milky Way (d=69 kpc). It is possibly a disrupted dSph interacting with the external Galactic halo. This...
