A confined flare above filaments
K. Dalmasse, R. Chandra, B. Schmieder +1
We present the dynamics of two filaments and a C-class flare observed in NOAA 11589 on 2012 October 16. We used the multi-wavelength high-resolution data from SDO, as well as THEMI…
Photospheric Injection of Magnetic Helicity: Connectivity--based Flux Density Method
K. Dalmasse, E. Pariat, P. Démoulin +1
Magnetic helicity quantifies how globally sheared and/or twisted is the magnetic field in a volume. This quantity is believed to play a key role in solar activity due to its conser…
Solar filament eruptions and their physical role in triggering Coronal Mass Ejections
B. Schmieder, P. Demoulin, G. Aulanier
Solar filament eruptions play a crucial role in triggering coronal mass ejections (CMEs). More than 80 % of eruptions lead to a CME. This correlation has been studied extensively d…
Global Dynamics of Subsurface Solar Active Regions
L. Jouve, A. S. Brun, G. Aulanier
We present three-dimensional numerical simulations of a magnetic loop evolving in either a convectively stable or unstable rotating shell. The magnetic loop is introduced in the sh…
Surface magnetic fields on two accreting T Tauri stars: CV Cha and CR Cha
G. A. J. Hussain, A. Collier Cameron, M. M. Jardine +12
We have produced brightness and magnetic field maps of the surfaces of CV Cha and CR Cha: two actively accreting G and K-type T Tauri stars in the Chamaeleon I star-forming cloud w…
