  • Publication
    On the Interaction Between Solar Photospheric Flow and Magnetic Fields
    The interaction between plasma flow and magnetic field transports magnetic energy and helicity through the photosphere. It plays an important role in driving...

  • Publication
    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...
  • Publication
    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...
