Slow magnetoacoustic gravity waves in an equilibrium stratified solar atmosphere: cut-off periods through the transition region
A. Costa, M. Schneiter, E. Zurbriggen
Assuming the thin flux tube approximation, we introduce an analytical model that contemplates the presence of: a non-isothermal temperature; a varying magnetic field and a non-unif…
MHD simulations of coronal supra-arcade downflows including anisotropic thermal conduction
E. Zurbriggen, A. Costa, A. Esquivel +2
Coronal supra-arcade downflows (SADs) are observed as dark trails descending towards hot turbulent fan shaped regions. Due to the large temperature values, and gradients in these f…
Two step chromospheric Moreton wave excitation in a blast-wave scenario. A case study: the December 06, 2006 event
G. Krause, M. Cécere, C. Francile +3
We examine the capability of a blast-wave scenario -associated to a coronal flare or to the expansion of CME flanks- to reproduce a chromospheric Moreton phenomenon. We also simula…
3D MHD simulation of flare supra-arcade downflows in a turbulent current sheet medium
M. Cécere, E. Zurbriggen, A. Costa +1
Supra-arcade downflows (SADs) are sunward, generally dark, plasma density depletions originated above posteruption flare arcades. In this paper using 3D MHD simulations we investig…
Simulation of descending multiple supra--arcade reconnection outflows in solar flares
M. Cécere, M. Schneiter, A. Costa +2
After recent AIA observations by Savage, McKenzie and Reeves we revisit the scenario proposed by us in previous papers. We have shown that sunward, generally dark plasma features o…
