Changes of Magnetic Energy and Helicity in Solar Active Regions from Major Flares
Yang Liu, Brian T. Welsch, Gherardo Valori +5
Magnetic free energy powers solar flares and coronal mass ejections (CMEs), and the buildup of magnetic helicity might play a role in the development of unstable structures that su…
An Observationally-Constrained Model of a Flux Rope that Formed in the Solar Corona
Alexander W. James, Gherardo Valori, Lucie M. Green +4
Coronal mass ejections (CMEs) are large-scale eruptions of plasma from the coronae of stars. Understanding the plasma processes involved in CME initiation has applications to space…
Magnetic helicity estimations in models and observations of the solar magnetic field. Part I: Finite volume methods
Gherardo Valori, Etienne Pariat, Sergey Anfinogentov +7
Magnetic helicity is a conserved quantity of ideal magneto-hydrodynamics characterized by an inverse turbulent cascade. Accordingly, it is often invoked as one of the basic physica…
