Observations of microwave emission from solar jets and comparison with MHD simulations
Costas E. Alissandrakis, Vasilis Archontis, Kostas Moraitis
We computed the thermal microwave emission from a 3D magnetohydrodynamic (MHD) simulation and compared it with observations of solar jets. The simulation treats the emergence of ma…
Magnetic helicity estimations in models and observations of the solar magnetic field. Part IV: Application to solar observations
J. K. Thalmann, M. K. Georgoulis, Y. Liu +8
In this ISSI-supported series of studies on magnetic helicity in the Sun, we systematically implement different magnetic helicity calculation methods on high-quality solar magnetog…
Relative field line helicity of a large eruptive solar active region
K. Moraitis, S. Patsourakos, A. Nindos
Context. Magnetic helicity is a physical quantity of great importance in the study of astrophysical and natural plasmas. Although a density for helicity cannot be defined, a good p…
Deducing the reliability of relative helicities from nonlinear force-free coronal models
Julia K. Thalmann, X. Sun, K. Moraitis +1
We study the relative helicity of active region (AR) NOAA~12673 during a ten-hour time interval centered around a preceding X2.2 flare (SOL2017-09-06T08:57) and also including an e…
The Solar Orbiter Science Activity Plan: translating solar and heliospheric physics questions into action
I. Zouganelis, A. De Groof, A. P. Walsh +182
Solar Orbiter is the first space mission observing the solar plasma both in situ and remotely, from a close distance, in and out of the ecliptic. The ultimate goal is to understand…
Additivity of relative magnetic helicity in finite volumes
Gherardo Valori, Pascal Démoulin, Etienne Pariat +3
Relative magnetic helicity is conserved by magneto-hydrodynamic evolution even in the presence of moderate resistivity. For that reason, it is often invoked as the most relevant co…
