Impact of Locally Suppressed Wave sources on helioseismic travel times
S. M. Hanasoge, S. Couvidat, S. P. Rajaguru +1
Wave travel-time shifts in the vicinity of sunspots are typically interpreted as arising predominantly from magnetic fields, flows, and local changes in sound speed. We show here t…

Contamination by Surface Effects of Time-distance Helioseismic Inversions for Sound Speed Beneath Sunspots
S. Couvidat, S. P. Rajaguru
Using Doppler velocity data from the SOI/MDI instrument onboard the SoHO spacecraft, we do time-distance helioseismic inversions for sound-speed perturbations beneath 16 sunspots o…
