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…

Global simulations of Tayler instability in stellar interiors: The stabilizing effect of gravity

G. Guerrero, F. Del Sordo, A. Bonanno +1

Unveiling the evolution of toroidal field instability, known as Tayler instability, is essential to understand the strength and topology of the magnetic fields observed in early-ty…

What sets the magnetic field strength and cycle period in solar-type stars?

G. Guerrero, B. Zaire, P. K. Smolarkiewicz +3

Two fundamental properties of stellar magnetic fields have been determined by observations for solar-like stars with different Rossby numbers (Ro), namely, the magnetic field stren…

Magnetic field generation in PMS stars with and without radiative core

Bonnie Zaire, Gustavo Guerrero, Alexander Kosovichev +2

Recent observations of the magnetic field in pre-main sequence stars suggest that the magnetic field topology changes as a function of age. The presence of a tachocline could be an…

On the role of repetitive magnetic reconnections in evolution of magnetic flux-ropes in solar corona

Sanjay Kumar, R. Bhattacharyya, Bhuwan Joshi +1

Parker's magnetostatic theorem extended to astrophysical magnetofluids with large magnetic Reynolds number supports ceaseless regeneration of current sheets and hence, spontaneous…

Understanding solar torsional oscillations from global dynamo models

G. Guerrero, P. K. Smolarkiewicz, E. M. de Gouveia Dal Pino +2

The phenomenon of solar "torsional oscillations" (TO) represents migratory zonal flows associated with the solar cycle. These flows are observed on the solar surface and, according…

Modelling turbulent stellar convection zones: sub-grid scales effects

A. Strugarek, P. Beaudoin, A. S. Brun +3

The impressive development of global numerical simulations of turbulent stellar interiors unveiled a variety of possible differential rotation (solar or anti-solar), meridional cir…

On the role of tachoclines in solar and stellar dynamos

G. Guerrero, P. K. Smolarkiewicz, E. M. de Gouveia Dal Pino +2

Rotational shear layers at the boundary between radiative and convective zones, tachoclines, play a key role in the process of magnetic field generation in solar-like stars. We pre…

Differential rotation in solar-like stars from global simulations

G. Guerrero, P. K. Smolarkiewicz, A. G. Kosovichev +1

To explore the physics of large-scale flows in solar-like stars, we perform 3D anelastic simulations of rotating convection for global models with stratification resembling the sol…
