Simulations of Global Solar Convection with a Fully Compressible CHORUS++ Code
Keiji Hayashi, Alexander G. Kosovichev, Chunlei Liang
Fluid-dynamics simulations of global solar convection are a critically important tool for assessing the dynamics of the solar interior. However, simulation studies with a fully com…
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…
