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…

Height Dependent Phase Shifts of Wave Pulses in the Lower Solar Atmosphere Measured with SUNRISE III
Andreas Lagg, H. N. Smitha, Sami K. Solanki +32
We report on the measurement of the height-dependent time shifts of wave pulses in the lower solar atmosphere from high-resolution spectro-polarimetric observations obtained with t…
