    A spectroscopic quadruple as a possible progenitor of sub-Chandrasekhar type Ia supernovae

    Binaries have received much attention as possible progenitors of type Ia supernova explosions1, but long-term gravitational effects2,3 in tight triple or quadruple systems could also play a key role in producing ...

    Carbon-enhanced metal-poor stars enriched in s-process and r-process elements

    We present an on-going project consisting of analysis of a sample of twenty-five metal-poor stars, most of them carbon-enriched and thus tagged carbon-enhanced metal-poor (CEMP) stars, observed with the high-r...

    Velocity Fields in Stellar Atmospheres Probed by Tomography

    A tomographic method to probe velocity fields within stellar atmospheres is described. It relies on the design of spectral masks collecting lines forming at given, pre-specified ranges of optical depths. Diffe...

    AGB Stars in Binaries and Their Progeny

    Although binarity and AGB evolution are in principle disconnected concepts (a star need not be member of a binary system to evolve along the AGB), a rich world flourishes at their contact. The interest in disc...

    Asymmetric Photoreactions as the Origin of Biomolecular Homochirality: A Critical Review

    The role of asymmetric photoreactions (occurringin space or on the primitive Earth) in the origin of biomolecularhomochirality is critically reviewed. A general description of thevarious possible ways for ligh...

    The Link between Barium Stars and Optically Bright Post-AGB Binaries

    Systematic radial velocity monitoring programs revealed that all optically bright, high-latitude post-AGB stars that show a near-IR excess in their energy distribution are binaries (see the contribution of R. ...
