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…

Helioseismic Evidence That the Solar Dynamo Originates near the Tachocline

Krishnendu Mandal, Alexander G. Kosovichev

The exact location of the solar dynamo remains uncertain--whether it operates primarily in the near-surface shear layer, throughout the entire convection zone, or near the tachocli…

3D Radiative MHD Modeling of Particle Beam Heating of the Solar Atmosphere

Samuel Granovsky, Alexander G. Kosovichev, Irina N. Kitiashvili +1

While solar flares are primarily associated with enhanced ultraviolet and X-ray emission, a subset of flares exhibit significant continuum brightening in visible light and are clas…
