Chromospheric Dynamics and Line Formation
R. Hammer, P. Ulmschneider
The solar chromosphere is very dynamic, due to the presence of large amplitude hydrodynamic waves. Their propagation is affected by NLTE radiative transport in strong spectral line…
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…
Acoustic wave propagation in the solar atmosphere. V. Observations versus simulations
J. Theurer, P. Ulmschneider, W. Kalkofen
We study the evolution of spectra of acoustic waves that are generated in the convection zone and propagate upward into the photosphere, where we compare the simulated acoustic spe…
Acoustic wave propagation in the solar atmosphere. IV Nonadiabatic wave excitation with frequency spectra
J. Theurer, P. Ulmschneider, M. Cuntz
We study the response of the solar atmosphere to excitations by large amplitude acoustic waves with radiation damping now included. Monochromatic adiabatic waves, due to unbalanced…
