Variation of solar irradiance and mode frequencies during Maunder minimum
A. Bhatnagar, Kiran Jain, S. C. Tripathy
Using the sunspot numbers reported during the Maunder minimum and the empirical relations between the mode frequencies and solar activity indices, the variations in the total solar…
How good are the predictions for oscillation frequencies
Kiran Jain, S. C. Tripathy, A. Bhatnagar
We have used available intermediate degree p-mode frequencies for the solar cycle 23 to check the validity of previously derived empirical relations for frequency shifts (Jain et a…
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…
Solar cycle induced variations in GONG p-mode frequencies and splittings
Kiran Jain, S. C. Tripathy, A. Bhatnagar
We have analysed the recently available GONG p-mode frequencies and splitting coefficients for a period of three and half years, including the rapidly rising phase of solar cycle 2…
Empirical estimate of p-mode frequency shift for solar cycle 23
Kiran Jain, S. C. Tripathy, A. Bhatnagar +1
We have obtained empirical relations between the p-mode frequency shift and the change in solar activity indices. The empirical relations are determined on the basis of frequencies…
