The Milky Way and the Local Group (MWLG)
  • Publication
    Local variations of the stellar velocity ellipsoid - II. The effect of the bar in the inner regions of Auriga galaxies
    Theoretical works have shown that off-plane motions of bars can heat stars in the vertical direction during buckling but is not clear how do they affect the...

    Low and High Temperature Infrared Spectroscopy of C60 and C70 Fullerenes
    The FT-IR spectra of the fullerenes C60 and C70 have been recorded in the temperature range between 523 K (+250 degrees C) and 93 K (-180 degrees C). As a...

    Low-amplitude rotational modulation rather than pulsations in the CoRoT B-type supergiant HD 46769
    Aims: We aim to detect and interpret photometric and spectroscopic variability of the bright CoRoT B-type supergiant target HD 46769 (V = 5.79). We also attempt...
  • Publication
    Low-frequency gravity waves in blue supergiants revealed by high-precision space photometry
    Almost all massive stars explode as supernovae and form a black hole or neutron star. The remnant mass and the impact of the chemical yield on subsequent star...
  • Publication
    Low-frequency photospheric and wind variability in the early-B supergiant HD 2905
    Context. Despite important advances in space asteroseismology during the last decade, the early phases of evolution of stars with masses above 15 M⊙ (including...
  • Publication
    Low-mass low-metallicity AGB stars as an efficient i-process site explaining CEMP-rs stars
    Context. Among carbon-enhanced metal-poor (CEMP) stars, some are found to be enriched in slow-neutron capture (s-process) elements (and are then tagged CEMP-s)...
  • Publication
    Low-resolution spectroscopy of main sequence stars belonging to 12 Galactic globular clusters. I. CH and CN band strength variations
    Context. Globular clusters show star-to-star abundance variations for light elements that are not yet well understood. The preferred explanation involves a self...
  • Publication
    Lucky spectroscopy, an equivalent technique to lucky imaging. II. Spatially resolved intermediate-resolution blue-violet spectroscopy of 19 close massive binaries using the William Herschel Telescope
    Context. Many massive stars have nearby companions. These hamper a characterization of massive stars through spectroscopy. Aims: We continue to obtain spatially...

    Lucky Spectroscopy, an equivalent technique to Lucky Imaging. Spatially resolved spectroscopy of massive close visual binaries using the William Herschel Telescope
    Context. Many massive stars have nearby companions whose presence hamper their characterization through spectroscopy. Aims: We want to obtain spatially resolved...
