Reconstructing Highly-twisted Magnetic Fields
Victor M. Demcsak, Michael S. Wheatland, Alpha Mastrano +1
We investigate the ability of a nonlinear force-free code to calculate highly-twisted magnetic field configurations using the Titov and Démoulin (1999) equilibrium field as a test…
A weak coronal heating event associated with periodic particle acceleration episodes
Atul Mohan, Patrick I. McCauley, Alpha Mastrano +1
Weak heating events are frequent and ubiquitous in solar corona. They derive their energy from the local magnetic field and form a major source of local heating, signatures of whic…
Nonlinear force-free modeling of flare-related magnetic field changes at the photosphere and chromosphere
Lucia Kleint, Michael S. Wheatland, Alpha Mastrano +1
Rapid and stepwise changes of the magnetic field are often observed during flares but cannot be explained by models yet. Using a 45 min sequence of SDO/HMI 135 s fast-cadence vecto…
Photospheric response to a flare
Michael S. Wheatland, Donald B. Melrose, Alpha Mastrano
Flares produce sudden and permanent changes in the horizontal photospheric magnetic field. In particular flares generally produce increased magnetic shear in the photospheric field…
Stability of magnetic fields in non-barotropic stars: an analytic treatment
Taner Akgün, Andreas Reisenegger, Alpha Mastrano +1
Magnetic fields in upper main-sequence stars, white dwarfs, and neutron stars are known to persist for timescales comparable to their lifetimes. From a theoretical perspective this…
Instability-driven interfacial dynamo in protoneutron stars
Alpha Mastrano, Andrew Melatos
The existence of a tachocline in the Sun has been proven by helioseismology. It is unknown whether a similar shear layer, widely regarded as the seat of magnetic dynamo action, als…
