High-resolution calculation of the solar global convection with the reduced speed of sound technique: II. Near surface shear layer with the rotation
H. Hotta, M. Rempel, T. Yokoyama
We present a high-resolution, highly stratified numerical simulation of rotating thermal convection in a spherical shell. Our aim is to study in detail the processes that can maint…
Time-Distance Helioseismology of Two Realistic Sunspot Simulations
K. DeGrave, J. Jackiewicz, M. Rempel
Linear time-distance helioseismic inversions are carried out using several filtering schemes to determine vector flow velocities within two $\sim100^2\,{\rm Mm^2}\times 20\,{\rm Mm…
Waves as the source of apparent twisting motions in sunspot penumbrae
L. Bharti, R. H. Cameron, M. Rempel +2
The motion of dark striations across bright filaments in a sunspot penumbra has become an important new diagnostic of convective gas flows in penumbral filaments. The nature of the…
Penumbral fine structure and driving mechanisms of large-scale flows in simulated sunspots
Matthias Rempel
We analyze in detail the penumbral structure found in a recent radiative MHD simulation. Near tau=1, the simulation produces penumbral fine structure consistent with the observatio…
Modeling the Subsurface Structure of Sunspots
H. Moradi, C. Baldner, A. C. Birch +19
While sunspots are easily observed at the solar surface, determining their subsurface structure is not trivial. There are two main hypotheses for the subsurface structure of sunspo…
