On the p-mode asymmetry between velocity and intensity from the GONG+ data
S. C. Tripathy, Kiran Jain, Frank Hill +1
We have analyzed the local acoustic spectra of small regions over the solar surface at different locations from disk center to limb via the technique of ring diagrams. It is found…

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…
