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…
Polarity relevance in flux rope deflections triggered by coronal holes
Abril Sahade, Mariana Cécere, Andrea Costa +1
Many observations show that coronal holes (CHs) deviate coronal mass ejections (CMEs) away from them. However, there are some peculiar events reported where the opposite occurs. To…
Slow and sausage loop mode excitation due to local and global spontaneous perturbations
H. Capettini, M. Cécere, A. Costa +2
We analyse the capability of different type of perturbations -associated with usual environment energy fluctuations of the solar corona- to excite slow and sausage modes in solar f…
Influence of coronal holes on CME deflections: numerical study
Abril Sahade, Mariana Cécere, Gustavo Krause
The understanding of the causes that produce the deflection of coronal mass ejections (CMEs) is essential for the space weather forecast. In this article, we study the effects on C…
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…
A Study of Radio Polarization in Protostellar Jets
Mariana Cécere, Pablo F. Velázquez, Anabella T. Araudo +4
Synchrotron radiation is commonly observed in connection with shocks of different velocities, ranging from relativistic shocks associated with active galactic nuclei, gamma-ray bur…
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…
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…
Numerical simulation of fundamental trapped sausage modes
M. Cécere, A. Costa, O. Reula
Context: We integrate the 2D MHD ideal equations of a straight slab to simulate observational results associated with fundamental sausage trapped modes. Aims: Starting from a non-e…
