The magnetic helicity driven solar-type dynamo
V. V. Pipin
(1)The previous theoretical studies showed that in the presence of the small-scale dynamo the large-scale vorticity can produce the the divergent-type helicity flux breaking the eq…
Effects of harmonic magnetic field boundary conditions in mean-field solar dynamo
V. V. Pipin
We consider effects of the harmonic magnetic field boundary conditions at the top of the dynamo domain on the dynamo stability inside the solar convection zone. These boundary cond…
Helicity Fluxes and Hemispheric Helicity Rule of Active Regions Emerging from the Convection Zone Dynamo
V. V. Pipin, Shangbin Yang, A. G. Kosovichev
Using a 3D non-linear mean-field solar dynamo model, we investigate the magnetic helicity flux and magnetic twist, and tilt parameters of bipolar magnetic regions (BMRs) emerging f…
Investigating Variations in Solar Differential Rotation by Helioseismology
Krishnendu Mandal, Alexander G. Kosovichev, Valery V. Pipin +1
Helioseismic signatures of dynamo waves have recently been discovered in variations of the solar differential rotation, offering valuable insights into the type of dynamo mechanism…
