    Molecules in the AGB Stars of Nearby Galaxies

    We obtained infrared spectra of Asymptotic Giant Branch (AGB) stars in nearby galaxies, and measured the equivalent widths of HCN and C2H2 bands for the carbon-rich stars, and SiO abundances for the oxygen-rich s...

    Old Stars in Dwarf Irregular Galaxies: WLM and NGC3109

    We present evidence for the existence of old stellar halos in the dwarf irregular galaxies WLM and NGC3109, located in the outskirts of the Local Group. These halos consist of metal-poor ([Fe/H] < -1) and old (t ...
