Formation and rising phase of a flux rope through data-constrained simulations

M. V. Sieyra, A. Strugarek, A. Prasad +8

Context. Data-constrained models incorporate observed photospheric magnetic fields. However, due to the lack of magnetic field information in the rest of the solar atmosphere, mode…

Energetics and Emission in a Simulated Solar Flare Initialised by a Non-Force Free Magnetic Field

W. Bate, M. Gordovskyy, A. Prasad +7

Solar flare simulations are commonly initialised using non-linear force free field (NLFF) extrapolations derived from photospheric vector magnetograms. However, the force free assu…

On the analysis of eruptive events with non-radial evolution

Abril Sahade, M. Valeria Sieyra, Mariana A. Cecere

Coronal mass ejections (CMEs) are major drivers of space weather disturbances, and their deflection from the radial direction critically affects their potential impact on Earth. Wh…

Uniturbulence and Alfven wave solar model

Tom Van Doorsselaere, M. Valeria Sieyra, Norbert Magyar +2

AWSOM-type models (Van der Holst et al. 2014) have been very successful in describing the solar atmosphere by incorporating the Alfven wave driving as extra contributions in the gl…

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…

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…

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…

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…
