Estimating the coronal supra-arcade downflows radio emission: from centimetre through submillimetre wavelengths
Ernesto Zurbriggen, C. Guillermo Giménez de Castro, Andrea Costa +2
Supra-arcade downflows (SADs) are infrequent, wiggly opaque structures observed to descend through the solar corona, mostly in EUV and soft X-ray frequencies. From their physical c…
An MHD Study of Large-Amplitude Oscillations in Solar Filaments
Ernesto Zurbriggen, Mariana Cécere, María Valeria Sieyra +3
Quiescent filaments are usually affected by internal and/or external perturbations triggering oscillations of different kinds. In particular, external large-scale coronal waves can…
Solar slow magneto-acoustic-gravity waves: an erratum correction and a revisited scenario
E. Zurbriggen, M. V. Sieyra, A. Costa +2
Slow waves are commonly observed on the entire solar atmosphere. Assuming a thin flux tube approximation, the cut-off periods of slow-mode magneto-acoustic-gravity waves that trave…
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…
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…
