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…
Structure and Dynamics of the Sun's Interior Revealed by Helioseismic and Magnetic Imager
Alexander Kosovichev, Sarbani Basu, Yuto Bekki +43
High-resolution helioseismology observations with the Helioseismic and Magnetic Imager (HMI) onboard Solar Dynamics Observatory (SDO) provide a unique three-dimensional view of the…
Probing Depth Variations of Solar Inertial Modes through Normal Mode Coupling
Krishnendu Mandal, Shravan M. Hanasoge
Recently discovered inertial waves, observed on the solar surface, likely extend to the deeper layers of the Sun. Utilizing helioseismic techniques, we explore these motions, allow…
Helioseismic Properties of Dynamo Waves in the Variation of Solar Differential Rotation
Krishnendu Mandal, Alexander G. Kosovichev, Valery V. Pipin
Solar differential rotation exhibits a prominent feature: its cyclic variations over the solar cycle, referred to as zonal flows or torsional oscillations, are observed throughout…
