Determining low- p-mode frequency shifts in Sun-like stars: Enhancing the cross-correlation technique with filters
Samarth G. Kashyap, Laurent Gizon, Jesper Schou +1
Acoustic mode frequencies in the Sun and Sun-like stars change due to magnetic activity, on time-scales much larger than the star's rotation and much smaller than its evolution. Gi…

Modelling the Center-to-Limb systematic in normal-mode-coupling measurements
Samarth G. Kashyap, Shravan M. Hanasoge
Solar meridional circulation, which manifests as poleward flow near the surface, is a relatively weak flow. While meridional circulation has been measured through various local hel…
