Context: HIP 96515 A is a double-lined spectroscopic binary included in the SACY catalog as a potential young star. It has a visual companion (CCDM 19371-5134 B, HIP 96515 B) at 8.6 arcsec. If bound to the primary, the optical and infrared colors of this wide companion are consistent with those of a white dwarf. Aims: We attempt to characterize the

The unseen population of F- to K-type companions to hot subdwarf stars
We present a method to select hot subdwarf stars with A- to M-type companions using photometric selection criteria. We cover a wide range in wavelength by combining Galaxy Evolution Explorer (GALEX) ultraviolet data, optical photometry from the Sloan Digital Sky Survey (SDSS) and the Carlsberg Meridian Telescope, near-infrared data from Two-Micron

The unusual V-type asteroid (2579) Spartacus
Asteroid (2579) Spartacus is a small V-type object located in the inner main belt (the main delivery region for meteorites). It shows spectral characteristics different from typical values for Vestoids, which may indicate origin deeper within Vesta then other V-types or a different parent body. We determine physical and dynamical properties of

The Unusual Vertical Mass Distribution of NGC 4013 Seen through the Spitzer Survey of Stellar Structure in Galaxies (S4G)
NGC 4013 is a nearby Sb edge-on galaxy known for its "prodigious" H I warp and its "giant" tidal stream. Previous work on this unusual object shows that it cannot be fitted satisfactorily by a canonical thin+thick disk structure. We have produced a new decomposition of NGC 4013, considering three stellar flattened components (thin+thick disk plus

The V-R Diagram - a Diagnostic Tool for the Dynamical Classification of Spiral Galaxies
The relations between the angular momentum (J) and the mass (M) for a sample of spiral galaxies are discussed for galaxies distributed in the rotational velocity (V) - size (R) plane. It is found that, for a given mass, Sc galaxies have larger angular momentum (~20%) than Sa. The absence of segregation in the angular momentum (J) - mass (M) plane
