    The long bar as seen by the VVV survey. I. Colour-magnitude diagrams
    Context. The VISTA Variable Survey (VVV) is able to map the Galaxy at l ≤ 0° with an unpaired depth (at least 3 mag deeper than 2MASS), opening new...
  • Publication
    The long bar as seen by the VVV Survey. II. Star counts
    Context. There is still some debate about the presence and the morphological properties of the long bar in the inner Galaxy. Aims: We investigate the...

    The Long Bar in the Milky Way: Corroboration of an Old Hypothesis
    Recent Galactic Legacy Infrared Mid-Plane Survey Extraordinaire data have further confirmed the hypothesis of the existence of an in-plane long bar different...

    The long Galactic bar as seen by UKIDSS Galactic plane survey
    Context: Over the past decade there have been a series of results supporting the hypothesis of the existence of a long thin bar in the Milky Way with a half...

    The long-period binary central stars of the planetary nebulae NGC 1514 and LoTr 5
    The importance of long-period binaries for the formation and evolution of planetary nebulae is still rather poorly understood, which in part is due to the lack...

    The long-term optical evolution of the black hole candidate MAXI J1659-152
    We present 5 yr of optical and infrared data of the black hole candidate MAXI J1659-152 covering its 2010 outburst, decay, and quiescence. Combining optical...

    The longest thermonuclear X-ray burst ever observed?. A BeppoSAX Wide Field Camera observation of 4U 1735-44
    A long flux enhancement, with an exponential decay time of 86 min, is detected in 4U 1735-44 with the BeppoSAX Wide Field Cameras. We argue that this is a type...

    The low L solar p-mode spectrum at maximum and minimum solar activity
    Velocity measurements of disc integrated sunlight obtained at the Observatorio del Teide (Izana) from 1980 throughout 1989 are used to find the frequencies and...

    The Low Metallicity Tail of the Halo Metallicity Distribution Function
    Ongoing spectroscopy and photometry of stars selected in the HK objective-prism/interference-filter survey of Beers and colleagues has resulted in the...
