Solar Atmospheric Heating Due to Small-scale Events in an Emerging Flux Region
Rahul Yadav, Maria D. Kazachenko, Andrey N. Afanasyev +2
We investigate the thermal, kinematic and magnetic structure of small-scale heating events in an emerging flux region (EFR). We use high-resolution multi-line observations (includi…
Hybrid data-driven magnetofrictional and magnetohydrodynamic simulations of an eruptive solar active region
A. Afanasyev, Y. Fan, M. Kazachenko +1
We present first results of the hybrid data-driven magnetofrictional (MF) and data-constrained magnetohydrodynamic (MHD) simulations of solar active region NOAA 11158, which produc…
Validation of the PDFI_SS method for electric field inversions using a magnetic flux emergence simulation
Andrey N. Afanasyev, Maria D. Kazachenko, Yuhong Fan +2
Knowledge of electric fields in the photosphere is required to calculate the electromagnetic energy flux through the photosphere and set up boundary conditions for data-driven magn…
Excitation of decay-less transverse oscillations of coronal loops by random motions
A. N. Afanasyev, T. Van Doorsselaere, V. M. Nakariakov
The relatively large-amplitude decaying regime of transverse oscillations of coronal loops has been known for two decades and interpreted in terms of MHD kink modes of cylindrical…
Coronal loop transverse oscillations excited by different driver frequencies
Andrey Afanasyev, Konstantinos Karampelas, Tom Van Doorsselaere
We analyse transverse oscillations of a coronal loop excited by continuous monoperiodic motions of the loop footpoint at different frequencies in the presence of gravity. Using the…
A Challenging Solar Eruptive Event of 18 November 2003 and the Causes of the 20 November Geomagnetic Superstorm. II. CMEs, Shock Waves, and Drifting Radio Bursts
V. V. Grechnev, A. M. Uralov, I. M. Chertok +7
We continue our study (Grechnev et al. (2013), doi:10.1007/s11207-013-0316-6; Paper I) on the 18 November 2003 geoffective event. To understand possible impact on geospace of coron…
