On the solar rotation rate in the upper convection zone
Kiran Jain, S. C. Tripathy, A. Bhatnagar
We present results on variation in rotation rate in the upper convection zone using data from GONG and MDI/SOHO covering a period of more than four years. We find that the first fe…

Temporal evolution of f-mode frequencies and radius
Kiran Jain, S. C. Tripathy, A. Bhatnagar
We have analysed temporal evolution in centroid frequencies and splitting coefficients of solar f-modes obtained from MDI/SOHO. The data were divided into 20 sets covering a period…
