Volumetric heating in coronal streamers
Wu, S. T.; Suess, S. T.; Wang, A. -H.
The addition of a volumetric heat source to a coronal streamer model produces distinct, important changes in the model. Originally, such heating was added to meet the observational requirement for a thin current sheet above streamers. Here we report additional consequences of a volumetric heat source, together with the effects of redistribution of…
Propagation of three-dimensional Alfvén waves in a stratified, thermally conducting solar wind
Orlando, S.; Peres, G.; Rosner, R. +1 more
We model the propagation of three-dimensional, adiabatic, linear Alfvén waves in the solar atmosphere and wind, taking into account relevant physical effects, including gravity stratification, thermal conduction, radiative losses, and heating (via a phenomenological term). Our magnetohydrodynamic solar wind model also accounts for the momentum dep…
