    On the k-mechanism and the multidimensional Eddington approximation
    The suitability of the Eddington approximation as a theoretical framework for the study of the possibility of a k-like overstability mechanism as the driving...

    On the Lack of Stellar Bars in Coma Dwarf Galaxies
    We present a study of the bar fraction in the Coma cluster galaxies based on a sample of ~190 galaxies selected from the SDSS-DR6 and observed with the Hubble...

    On the light-curve of OT/GRB970508
    Using the Nordic Optical Telescope, La Palma, Spain, optical studies of OT/GRB970508 were initiated 3 hours 5 minutes after the high energy event (This appears...
  • Publication
    On the Light-Profiles of Spiral Galaxy Bulges and the Hubble Sequence for Spirals
    Recent studies have claimed that the Hubble sequence of late-type spirals, and spirals in general, is scale-free. Within the photometric data used in these...
  • Publication
    On the Limits of Seismic Inversions for Radial Differential Rotation of Solar-Type Stars
    Seismic data contains information on stellar internal rotation, which plays an important role on dynamo models. Due to the uncertainties on the observations and...
  • Publication
    On The Magnetic-Field Diagnostics Potential of SDO/HMI
    The Helioseismic and Magnetic Imager (HMI) onboard the Solar Dynamics Observatory (SDO) is designed to study oscillations and the magnetic field in the solar...
  • Publication
    On the making of a PN: the interaction of a multiple stellar wind with the ISM
    NGC 7293, the Helix nebula, represents one of the rare instances in which theoretical predictions of stellar evolution can be accurately tested against...
  • Publication
    On the MG 2 and Fe 2 resonance lines in Herbig AE stars: Preliminary results
    The IUE observed AB Aur, HD250550, and BD + 46 deg 3471 at high resolution in the range 2000 to 32000 A. The MgII resonance line profiles all show a P Cygni...
