Nonlinear steepening of a fast magnetoacoustic wave in the vicinity of a coronal magnetic null point
Yu Zhong, Valery M. Nakariakov, Mariana Cécere +1
The interaction of a fast magnetoacoustic wave with a magnetic null point is studied in the context of the sympathetic flare phenomenon. Attention is paid to steepening the wave ca…
Observational and numerical characterization of a recurrent arc-shaped front propagating along a coronal fan
M. V. Sieyra, S. Krishna Prasad, G. Stenborg +5
Recurrent, arc-shaped intensity disturbances were detected by EUV channels in an active region. The fronts were observed to propagate along a coronal loop bundle rooted in a small…
Pseudostreamer influence on flux rope evolution
A. Sahade, M. Cécere, M. V. Sieyra +3
A critical aspect of solar activity is the coupling between eruptions and the surrounding coronal magnetic field, which determines the trajectory and morphology of the eruptive eve…
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…
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…
Analysis of large deflections of prominence-CME events during the rising phase of solar cycle 24
M. V. Sieyra, M. Cécere, H. Cremades +7
Motivated by the need to improve the ability to forecast whether a certain coronal mass ejection (CME) is to impact Earth, and by the insufficiency of statistical studies that anal…
