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.…
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…
Analysis of hysteresis effect in p mode frequency shifts and solar activity indices
S. C. Tripathy, Brajesh Kumar, Kiran Jain +1
Using intermediate degree p mode frequency data sets for solar cycle 22, we find that the frequency shifts and magnetic indices show a `hysteresis' phenomenon. It is observed that…
