Dynamics of the Solar Magnetic Network. II. Heating the Magnetized Chromosphere
S. S. Hasan, A. A. van Ballegooijen
We consider recent observations of the chromospheric network, and argue that the bright network grains observed in the Ca II H & K lines are heated by an as yet unidentified quasi-…
Probing the internal magnetic field of slowly pulsating B-stars through g modes
S. S. Hasan, J. -P. Zahn, J. Christensen-Dalsgaard
We suggest that high-order g modes can be used as a probe of the internal magnetic field of SPB (slowly pulsating B) stars. The idea is based on earlier work by the authors which a…
Dynamics of the Solar Magnetic Network: Two-dimensional MHD Simulations
S. S. Hasan, A. A. van Ballegoiijen, W. Kalkofen +1
The aim of this work is to identify the physical processes that occur in the network and contribute to its dynamics and heating. We model the network as consisting of individual fl…
Dynamics and Heating of the Magnetic Network on the Sun: Efficiency of mode transformation
S. S. Hasan, P. Ulmschneider
We aim to identify the physical processes which occur in the magnetic network of the chromosphere and which contribute to its dynamics and heating. Specifically, we study the propa…
