Time-Dependence of Subsurface Solar Convection Using the Time-Distance Deep-Focus Method

John T. Stefan, Alexander G. Kosovichev, Gustavo Guerrero +1

We re-examine the deep-focus methodology of time-distance helioseismology previously used to estimate the power spectrum of the solar convection at a depth of about 30 Mm, which wa…

Can Proton Beam Heating Flare Models Explain Sunquakes?

Viacheslav Sadykov, John Stefan, Alexander Kosovichev +4

SDO/HMI observations reveal a class of solar flares with substantial energy and momentum impacts in the photosphere, concurrent with white-light emission and helioseismic responses…

The Puzzling Structure of Solar Convection: Window into the Dynamo

Nicholas A. Featherstone, Kyle C. Augustson, Jonathan M. Aurnou +25

The operation of the solar dynamo, with all of its remarkable spatio-temporal ordering, remains an outstanding problem of modern solar physics. A number of mechanisms that might pl…

Implicit large eddy simulations of global solar convection: effects of numerical resolution in non-rotating and rotating cases

G. Guerrero, A. M. Stejko, A. G. Kosovichev +2

Simulating deep solar convection and its coupled mean-field motions is a formidable challenge where few observational results constrain models that suffer from the non-physical inf…

Constraining Global Solar Models through Helioseismic Analysis

Andrey M. Stejko, Alexander G. Kosovichev, Nicholas A. Featherstone +4

Global hydrodynamic simulations of internal solar dynamics have focused on replicating the conditions for solar-like differential rotation and meridional circulation using the resu…

Advances and Challenges in Observations and Modeling of the Global-Sun Dynamics and Dynamo

A. G. Kosovichev, G. Guerrero, A. M. Stejko +2

Computational heliophysics has shed light on the fundamental physical processes inside the Sun, such as the differential rotation, meridional circulation, and dynamo-generation of…
