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.…
