Latitude-Dependent Time Variations of the Solar Tachocline
Sarbani Basu, Sylvain G. Korzennik, Sushanta C. Tripathy
We have examined how the characteristics of the tachocline -- i.e., the change in rotation rate , or the "jump", the position of the midpoint of the tachocline, , and th…
Dynamics of Subsurface Flows in Solar Active Regions During the May 2024 Storm
B Lekshmi, Sushanta Tripathy, Kiran Jain +1
In May 2024, the Sun exhibited intense magnetic activity, marked by numerous high-intensity flares resulting from the interaction and merging of NOAA ARs 13664 and 13668 in the sou…
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…
Seismic differences between solar magnetic cycles 23 and 24 for low-degree modes
Rafael A. Garcia, Sylvain N. Breton, David Salabert +4
Solar magnetic activity follows regular cycles of about 11 years with an inversion of polarity in the poles every 22 years. This changing surface magnetism impacts the properties o…
