What Solar Oscillation Tell us About the Solar Minimum
Kiran Jain, S. C. Tripathy, O. Burtseva +6
The availability of continuous helioseismic data for two consecutive solar minima has provided a unique opportunity to study the changes in the solar interior that might have led t…
Variation of Acoustic Power with Magnetic Field as seen in Gong+ Data
P. Venkatakrishnan, Brajesh Kumar, S. C. Tripathy
The acoustic spectra in sunspots are known to be richer in higher frequency power. We have attempted a generalized study of the effect of magnetic fields on the shape of the acoust…
Search for Spatial Variability in the Solar Acoustic Spectrum
P. Venkatakrishnan, Brajesh Kumar, S. C. Tripathy
Motivated by the various examples of spatial variability in the power of the acoustic spectrum, we attempted to look for spatial variability in the peak frequency of the spectrum.…
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…
p-modes in and away from a sunspot
Brajesh Kumar, R. Jain, S. C. Tripathy +2
A time series of GONG Dopplergrams for the period 10-14 May 1997 from Udaipur and Big Bear sites has been used to measure the velocity fluctuations in the sunspot (NOAA active regi…
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…
