    Spatial source distribution of bulges from surface photometry: application to NGC 2841.
    We tackle here the problem of obtaining the spatial density of sources ρ in the bulge of a spiral galaxy using bidimensional surface photometry. V,R,I,Z CCD...

    Spatially resolved measurements of the solar photospheric oxygen abundance
    Aims: We report the results of a novel determination of the solar oxygen abundance using spatially resolved observations and inversions. We seek to derive the...

    Spatially resolved near-infrared spectroscopy of the massive star-forming region IRAS 19410+2336
    Aims: IRAS 19410+2336 is a young massive star forming region with an intense outflow activity. Outflows are frequently studied in the near-infrared (NIR) since...

    Spatially Resolved Spectroscopy of Wolf-Rayet Ring Nebulae - Part Four - the Fundamental Parameters of the Central Stars
    We derive effective temperatures, luminosities and related parameters for a sample of eight Wolf-Rayet stars - seven WN stars and a WO star - by computing...

    Spatially resolving the dust properties and submillimetre excess in M 33
    Context. The relative abundance of the dust grain types in the interstellar medium is directly linked to physical quantities that trace the evolution of...

    Spatially-resolved dust properties of the GRB 980425 host galaxy
    Gamma-ray bursts (GRBs) have been proposed as a tool for studying star formation in the Universe, so it is crucial to investigate whether their host galaxies...

    Spectral analysis of early-type stars using a genetic algorithm based fitting method
    We present the first automated fitting method for the quantitative spectroscopy of O- and early B-type stars with stellar winds. The method combines the non-LTE...

    Spectral analysis of high resolution near-infrared spectra of ultra cool dwarfs
    Aims:We present an analysis of high resolution spectra in the J band of five ultra cool dwarfs from M6 to L0. Methods: We make use of a new ab initio water...
