    Do spiral arms enhance star formation efficiency?
    Spiral arms, as those of our own Milky Way, are some of the most spectacular features in disc galaxies. It has been argued that star formation should proceed...

    Does the virial mass drive the intra-cluster light?. Relationship between the ICL and M<SUB>vir</SUB> from VEGAS
    In this Letter, we revisit the relationship between the fraction of the intra-cluster light (ICL) as well as the virial mass and the fraction of early-type...

    Doppler images of the RS CVn binary HR 1099 (V711 Tau) from the MUSICOS 1998 campaign
    We present Doppler Images of the RS CVn binary system HR 1099 (V711 Tau) from spectra taken in two different sites, KPNO and MSO, during the MUSICOS 1998...

    Doppler tomography of the black hole binary A0620-00 and the origin of chromospheric emission in quiescent X-ray binaries
    Context. Doppler tomography of emission line profiles in low-mass X-ray binaries allows us to disentangle the different emission sites and study the structure...

    Doppler tomography of the transient X-ray binary Centaurus X-4 in quiescence
    We present ESO-NTT low resolution spectroscopy of the neutron star X-ray transient Cen X-4 in quiescence over a complete orbital cycle. Our data reveal the...

    Doppler tomography of transiting exoplanets: a prograde, low-inclined orbit for the hot Jupiter CoRoT-11b
    We report the detection of the Doppler shadow of the transiting hot Jupiter CoRoT-11b. Our analysis is based on line-profile tomography of time-series, Keck...

    Double-barred galaxies. I. A catalog of barred galaxies with stellar secondary bars and inner disks
    I present a catalog of 67 barred galaxies which contain distinct, elliptical stellar structures inside their bars. Fifty of these are double-barred galaxies: a...

    Double-peak structure in the cyclic optical outbursts of blazar OJ 287.
    An international monitoring project, called OJ-94, was set up with the aim of monitoring blazar OJ 287 during the predicted optical outburst (in fall 1994...

    Downflowing umbral flashes as evidence of standing waves in sunspot umbrae
    Context. Umbral flashes are sudden brightenings commonly visible in the core of some chromospheric lines. Theoretical and numerical modeling suggests that they...
