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...
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...
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...
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...
