    Superbursts at near-Eddington mass accretion rates
    Models for superbursts from neutron stars involving carbon shell flashes predict that the mass accretion rate should be anywhere in excess of one tenth of the...

    The afterglow and kilonova of the short GRB 160821B
    GRB 160821B is a short duration gamma-ray burst (GRB) detected and localized by the Neil Gehrels Swift Observatory in the outskirts of a spiral galaxy at z = 0...

    The CARMENES search for exoplanets around M dwarfs. Rubidium abundances in nearby cool stars
    Due to their ubiquity and very long main-sequence lifetimes, abundance determinations in M dwarfs provide a powerful and alternative tool to GK dwarfs to study...

    The chemical composition of R-stars
    The preliminary results of the chemical analysis of a sample of 22 galactic R-stars with measured parallaxes are presented. We have derived the C/O and 12C/13C...

    The chemical composition of TS 01, the most oxygen-deficient planetary nebula. AGB nucleosynthesis in a metal-poor binary star
    The planetary nebula TS 01 (also called PN G 135.9+55.9 or SBS 1150+599A) with its record-holding low oxygen abundance and its double degenerate close binary...

    The chemical evolution of globular clusters - I. Reactive elements and non-metals
    We propose a new chemical evolution model aimed at explaining the chemical properties of globular clusters (GCs) stars. Our model depends upon the existence of...

    The Cosmic NeuTRIVIA game
    In this talk, we shall review the impact of the neutrino properties on the different cosmological observables. We shall also present the latest cosmological...

    The Cygnus X region: a nucleosynthesis laboratory for INTEGRAL
    The detection of 1.809 MeV gamma-ray line emission from the Cygnus X complex by the COMPTEL telescope is one of the most convincing proves of massive star...

    The evolution of the Light Elements, Be and B (also Li), in the Galaxy
    We consider the evolution of the light elements, especially beryllium and boron but also lithium, in the Galaxy as derived from observations within 1 kpc of the...
