    Influence of phase-diversity image reconstruction techniques on circular polarization asymmetries
    Context. Full Stokes filter-polarimeters are key instruments for investigating the rapid evolution of magnetic structures on the solar surface. To this end, the...

    Infrared observations of binary stars. II
    Near infrared photometry is presented for the close eclipsing binaries R CMa, TX UMa, delta Lib, TV Cas, and AR Lac. The data are used to place limits on mass...

    Infrared observations of peculiar carbon stars.
    We present a uniform and high quality set of infrared photometric (JHK) observations of the 6 peculiar carbon giant stars V Ari, UV Cam, BD+34 911, TU Gem, BD...

    Infrared radial velocities of vB 10
    We present radial velocities of the M8V-type, very low-mass star vB 10 obtained at four different epochs between 2001 and 2008. We use high-resolution (R ~ 20...

    Infrared spectroscopy of the largest known trans-Neptunian object 2001 KX75
    We report complete near-infrared (0.9-2.4 mu m) spectral observations of the largest know trans-Neptunian objects (TNO) 28976 = 2001 KX76 taken in two different...

    Infrared spectroscopy of V616 Monocerotis (=A0620-00): the accretion disc contamination
    We have obtained for the first time K-band infrared spectra of the soft X-ray transient V616 Mon (=A0620-00). We determine the 2-sigma upper limit to the...

    Inner and outer rings are not strongly coupled with stellar bars
    Rings are distinctive features of many disc galaxies and their location and properties are closely related to the disc dynamics. In particular, rings are often...

    iNNterpol: High-precision interpolation of stellar atmospheres with a deep neural network using a 1D convolutional auto encoder for feature extraction
    Context. Given the widespread availability of grids of models for stellar atmospheres, it is necessary to recover intermediate atmospheric models by means of...

    Inside-out formation of nuclear discs and the absence of old central spheroids in barred galaxies of the TIMER survey
    The centres of disc galaxies host a variety of structures built via both internal and external processes. In this study, we constrain the formation and...
