Variation of Oscillation Mode Parameters over the Solar Cycle 23: An Analysis on Different Time Scales
S. C. Tripathy, F. Hill, K. Jain +1
We investigate the variation in the mode parameters obtained from time series of length 9, 36, 72 and 108 days to understand the changes occurring on different time-scales. The reg…

Correlation Analysis of Mode Frequencies with Activity Proxies at Different Phases of the Solar Cycle
Kiran Jain, S. C. Tripathy, F. Hill
We analyze intermediate degree p- and f-mode eigenfrequencies measured by GONG and MDI/SOHO for a complete solar cycle to study their correlation with solar activity. We demonstrat…

Does the Selection of a Quiet Region Influence the Local Helioseismic Inferences?
S. C. Tripathy, H. M. Antia, K. Jain +1
We apply the ring-diagram technique to high resolution Dopplergrams in order to estimate the variation in oscillation mode parameters between active and quiet regions. We demonstra…
