3D MHD Modeling of the Impact of Subsurface Stratification on the Solar Dynamo
Andrey M. Stejko, Gustavo Guerrero, Alexander G. Kosovichev +1
Various models of solar subsurface stratification are tested in the global EULAG-MHD solver to simulate diverse regimes of near-surface convective transport. Sub- and superadiabaci…
Estimation of Key Sunquake Parameters through Hydrodynamic Modeling and Cross-Correlation Analysis
John T. Stefan, Alexander G. Kosovichev
Sunquakes are one of the more distinct secondary phenomena related to solar flares, where energy deposition in the lower layers of the Sun's atmosphere excites acoustic waves easil…
Sunquakes of Solar Cycle 24
I. N. Sharykin, A. G. Kosovichev
The paper presents results of a search for helioseismic events (sunquakes) produced by M-X class solar flares during Solar Cycle 24. The search is performed by analyzing photospher…
On the Origin of Solar Torsional Oscillations and Extended Solar Cycle
V. V. Pipin, A. G. Kosovichev
We present a nonlinear mean-field model of the solar interior dynamics and dynamo, which reproduces the observed cyclic variations of the global magnetic field of the Sun, as well…
Response of SDO/HMI observables to heating of the solar atmosphere by precipitating high-energy electrons
Viacheslav M Sadykov, Alexander G Kosovichev, Irina N Kitiashvili +1
We perform an analysis of the line-of-sight (LOS) observables of the SDO/HMI for models of the solar atmosphere heated by precipitating high-energy electrons during solar flares. T…
Evolution of Magnetic Helicity in Solar Cycle 24
Valery V. Pipin, Alexei A. Pevtsov, Yang Liu +1
We propose a novel approach to reconstruct the surface magnetic helicity density on the Sun or sun-like stars. The magnetic vector potential is determined via decomposition of vect…
