    Nebular emission and the Lyman continuum photon escape fraction in CALIFA early-type galaxies
    We use deep integral field spectroscopy data from the CALIFA survey to study the warm interstellar medium (wim) over the entire extent and optical spectral...

    Neutral carbon and highly excited CO in a massive star-forming main sequence galaxy at z = 2.2
    We used the Plateau De Bure Interferometer to observe multiple CO and neutral carbon transitions in a z = 2.2 main sequence disk galaxy, BX610. Our observation...

    New and updated stellar parameters for 71 evolved planet hosts. On the metallicity-giant planet connection<xref ref-type="fn" rid="FN1"><xref ref-type="fn" rid="FN2">⋆<xref ref-type="fn" rid="FN3">⋆⋆
    Context. It is still being debated whether the well-known metallicity-giant planet correlation for dwarf stars is also valid for giant stars. For this reason...

    New and updated stellar parameters for 90 transit hosts. The effect of the surface gravity
    Context. Precise stellar parameters are crucial in exoplanet research for correctly determining the planetary parameters. For stars hosting a transiting planet...

    New candidate planetary nebulae in M 81
    A 34'x34' field centred on the spiral galaxy M 81 has been searched for emission-line objects using the prime focus wide field camera (WFC) of the 2.54 m Isaac...

    New constraints on the formation and settling of dust in the atmospheres of young M and L dwarfs
    Context. Gravity modifies the spectral features of young brown dwarfs (BDs). A proper characterization of these objects is crucial for the identification of the...

    New constraints on the membership of the T dwarf S Ori 70 in the σ Orionis cluster
    Aims:The nature of S Ori 70 (S Ori J053810.1-023626), a faint mid-T type object found towards the direction of the young σ Orionis cluster, is still under...

    New constraints on the presence of debris disks around G 196-3 B and VHS J125601.92-125723.9 b
    Context. The existence of warm (protoplanetary) disks around very young isolated planetary and brown dwarf mass objects is known based on near- and mid-infrared...
