    \(^{7}\) Be(n,p) \(^{7}\) Li Cross Section Measurement for the Cosmological Lithium Problem at the n \(\_\) TOF Facility at CERN

    One of the most puzzling problems in Nuclear Astrophysics is the “Cosmological Lithium Problem”, i.e the discrepancy between the primordial abundance of

    The Evolution of CNO Isotope Ratios: A Litmus Test for Stellar IMF Variations in Galaxies Across Cosmic Time

    Determining the shape of the stellar initial mass function (IMF) and whether it is constant or varies in space and time is the Holy Grail of modern astrophysics, with profound implications for all theories of ...

    Chemical Evolution of Late-Type Dwarfs

    After reviewing some general properties of late-type dwarf galaxies, we present and discuss chemical evolution models for two windy starburst dwarfs: NGC 1569 and NGC1705. Both have their recent star formation...

    The Effects of Pop III Stars on the Abundances of Spheroids

    We have studied the effects of an hypothetical initial generation made only of very massive stars (M > 100M ⊙, pair-creation SNe) on the chemical and photometric evolution of spheroidal sy...

    The Chemical Evolution of Dwarf Spheroidals

    We describe some models for the chemical evolution of dwarf spheroidals of the Local Group: Draco, Sagittarius, Sculptor, Sextan, Ursa Minor and Carina. These models assume one long or at maximum two episodes ...

    N/O Abundance Ratios: Milky Way and DLAs

    It has been recently shown in Chiappini et al. [2] that models of chemical evolution computed with the Meynet & Maeder [4] yields for the whole range of masses, predict a slower increase of N with respect to w...

    Metallicity in Open Clusters

    We present here the results of abundance measurements of iron, calcium and nickel in four open clusters, from UVES spectra of solar–type stars. A code developed by one of the authors (François) performs line r...

    A new Picture for the Galaxy Formation

    The observational constraints are of fundamental importance to build a realistic chemical evolution model. With respect to these constraints the last years have been of crucial importance and, in the case of t...

    The Chemical Evolution of the Galactic Bulge

    In this paper we review the chemical evolution models for the Galactic bulge: in particular, we discuss the predictions of models as compared with the available abundance data and infer the mechanism as well a...

    Synthetic integrated fluxes and colours for elliptical galaxies

    Photometric intergrated colours (UBVRI+UV selected bands) of elliptical galaxies are theoretically evaluated, accounting for stellar populations of different metal abundance (0.00001≤Z≤0.04). The contribution of ...

    LTE/non-LTE boundary from wide-band color index and bolometric correction comparison

    LTE/non-LTE boundary has been derived from the analysis of the flux data from atmospheric models. The derived border line seems to be like a reasonable extension at low logg's of the Kudritzki line (Kudritzki, 19...
