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…
The magnetohydrodynamic equations in terms of waveframe variables
Tom Van Doorsselaere, Norbert Magyar, M. Valeria Sieyra +1
Generalising the Elsasser variables, we introduce the Q-variables. These are more flexible than the Elsasser variables, because they also allow to track waves with phase speeds dif…
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…
Refined physical parameters for Chariklo's body and rings from stellar occultations observed between 2013 and 2020
B. E. Morgado, B. Sicardy, F. Braga-Ribas +78
The Centaur (10199) Chariklo has the first rings system discovered around a small object. It was first observed using stellar occultation in 2013. Stellar occultations allow the de…
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…
A 3D MHD simulation of SN 1006: a polarized emission study for the turbulent case
P. F. Velázquez, E. M. Schneiter, E. M. Reynoso +6
Three dimensional magnetohydrodynamical simulations were carried out in order to perform a new polarization study of the radio emission of the supernova remnant SN 1006. These simu…
