    Near-infrared spectroscopy of the Sulamitis asteroid family: Surprising similarities in the inner belt primitive asteroid population
    We present NIR spectra of 19 asteroids in the Sulamitis family as part of our survey of primitive inner belt asteroid families. The spectra were obtained with...

    New polarimetric and spectroscopic evidence of anomalous enrichment in spinel-bearing calcium-aluminium-rich inclusions among L-type asteroids
    Asteroids can be classified into several groups based on their spectral reflectance. Among these groups, the one belonging to the L-class in the taxonomic...

    NGC 6946: kinematics of the starburst in the circum-nuclear zone.
    Using spectroscopic observations at relatively high resolution (Δλ ≡ 0.35 Å) in the region within 30 arcseconds of the nucleus of NGC 6946 the authors have...

    Observations of Jupiter around 80 microns at high spectral resolution
    High-resolution (up to 0.02 kayser) airborne spectral observations of Jupiter in the range from 105 to 140 kaysers are presented. The procedures used to remove...

    On the Use of Field RR Lyrae as Galactic Probes. III. The α-element Abundances
    We provide the largest and most homogeneous sample of α-element (Mg, Ca, Ti) and iron abundances for field RR Lyrae (RRLs; 162 variables) by using high...

    On the Use of Field RR Lyrae As Galactic Probes: IV. New Insights Into and Around the Oosterhoff Dichotomy
    We discuss the largest and most homogeneous spectroscopic data set of field RR Lyrae variables (RRLs) available to date. We estimated abundances using both high...

    Orbital Torus Imaging: Using Element Abundances to Map Orbits and Mass in the Milky Way
    Many approaches to galaxy dynamics assume that the gravitational potential is simple and the distribution function is time invariant. Under these assumptions...
