  • Publication
    On the origin of stars with and without planets. Tc trends and clues to Galactic evolution
    We explore a sample of 148 solar-like stars to search for a possible correlation between the slopes of the abundance trends versus condensation temperature...
  • Publication
    On the origin of the absorption features in SS433
    We present high-resolution optical spectroscopy of the X-ray binary system SS433, obtained over a wide range of orbital phases. The spectra display numerous...
  • Publication
    On the origin of the angular momentum of galaxies: cosmological tidal torques supplemented by the Coriolis force
    We present here a theoretical model which can at least contribute to the observed relation between the specific angular momenta of galaxies and their masses...
  • Publication
    On the Origin of the Color-Magnitude Relation in the Virgo Cluster
    We explore the origin of the color-magnitude relation (CMR) of early-type galaxies in the Virgo Cluster using spectra of very high signal-to-noise ratio for six...
  • Publication
    On the origin of the compact H ii regions around massive stellar clusters
    The existence of compact H ii regions around massive stellar clusters with ages exceeding several Myr challenges our understanding of the physical processes...
  • Publication
    On the Origin of the Dispersion in the 7Li/6Li Ratio in the ISM
    Measurements of the 7Li/6Li ratio in the local interstellar medium (ISM) towards o Per and ζ Per by Knauth et al. (2000, AAA 073.131.129) show clouds with a...
  • Publication
    On the Origin of the Type II Spicules: Dynamic Three-dimensional MHD Simulations
    Recent high temporal and spatial resolution observations of the chromosphere have forced the definition of a new type of spicule, "type II's," that are...
  • Publication
    On the origin of the ultramassive white dwarf GD50
    We argue on the basis of astrometric and spectroscopic data that the ultramassive white dwarf GD50 is associated with the star formation event that created the...
  • Publication
    On the origin of the γ-ray emission from the flaring blazar PKS 1222+216
    The flat-spectrum radio quasar PKS 1222+216 (4C+21.35, z = 0.432) was detected in the very high energy γ-ray band by MAGIC during a highly active γ-ray phase...
