    On the Nature of Damped LYα Systems: Clues from Determinations of Elemental Abundance Ratios
    We present a study of the [α/Fe-peak] and [N/α] abundance ratios in Damped Lyα (DLA) systems. By using ratios of undepleted elements ([S/Zn] and [N/S]) or when...

    On the nature of starburst galaxies at low-z and their connection with interactions
    We investigate the properties of starbursts and the influence of galaxy-galaxy interactions on star formation (SF) in a sample of 1341 objects (distances < 40...

    On the nature of VX Sagitarii: Is it the first galactic super-AGB star found?
    Stars with initial masses above ~10 M ⊙ have an internal evolution completely different from those in the range between 4 and ~10 M ⊙. The former are able to...
