    Spectroscopy of Giants of the Sagittarius Dwarf Galaxy

    In this paper we present the first results of the analysis of intermediate resolution (Δλ ∼ 3.5 Å) spectra of giants of the Sagittarius dwarf galaxy acquired using the ESO NTT telescope. From the deep CCD phot...

    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 abundances of refractory elements are corrected b...

    The local interstellar medium: A test-bed for the galactic ISM

    We outline a method to explore the column density of the Local Interstellar Medium (LISM) using absorptions in the resonance H and K lines of Mgii. The intrinsic strengths of these lines in the temperature and de...

    Some considerations on the non-detection of interstellar Li and B towards the SN1987a

    A very low upper limit of 0.15 mÅ for the interstellar λ6707 Å Lii line has been recently derived towards the SN1987a by Baade and Magain (1988). This value corresponds toN(Li)<1.4×1011 cm−2 and gives [Li/H]<5.4×...
