Three-dimensional, Time-dependent MHD Simulation of Disk-Magnetosphere-Stellar Wind Interaction in a T Tauri, Protoplanetary System
Ofer Cohen, Cecilia Garraffo, Jeremy Drake +4
We present a three-dimensional, time-dependent, MHD simulation of the short-term interaction between a protoplanetary disk and the stellar corona in a T Tauri system. The simulatio…
Revisiting the space weather environment of Proxima Centauri b
Cecilia Garraffo, Julián D. Alvarado-Gómez, Ofer Cohen +1
Close-in planets orbiting around low-mass stars are exposed to intense energetic photon and particle radiation and harsh space weather. We have modeled such conditions for Proxima…
Comparing the Performance of a Solar Wind model from the Sun to 1 AU using Real and Synthetic Magnetograms
Kalpa Henadhira Arachchige, Ofer Cohen, Andrés Muñoz Jaramillo +1
The input of the Solar wind models plays a significant role in accurate solar wind predictions at 1 AU. This work introduces a synthetic magnetogram produced from a dynamo model as…
Stellar Energetic Particle Transport in the Turbulent and CME-disrupted Stellar Wind of AU~Microscopii
F. Fraschetti, J. D. Alvarado-Gómez, J. J. Drake +2
Energetic particles emitted by active stars are likely to propagate in astrospheric magnetized plasma turbulent and disrupted by the prior passage of energetic Coronal Mass Ejectio…
Simulating the Space Weather in the AU Mic System: Stellar Winds and Extreme Coronal Mass Ejections
Julián D. Alvarado-Gómez, Ofer Cohen, Jeremy J. Drake +7
Two close-in planets have been recently found around the M-dwarf flare star AU Microscopii (AU Mic). These Neptune-sized planets (AU Mic b and c) seem to be located very close to t…
Coronal Mass Ejections and Exoplanets: A Numerical Perspective
Julián D. Alvarado-Gómez, Jeremy J. Drake, Ofer Cohen +3
Coronal mass ejections (CMEs) are more energetic than any other class of solar phenomena. They arise from the rapid release of up to erg of magnetic energy mainly in the…
