    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...

    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...
