Prospects for the Detection of the Deep Solar Meridional Circulation
D. C. Braun, A. C. Birch
We perform helioseismic holography to assess the noise in p-mode travel-time shifts which would form the basis of inferences of large-scale flows throughout the solar convection zo…

Surface-focused Seismic Holography of Sunspots: I. Observations
D. C. Braun, A. C. Birch
We present a comprehensive set of observations of the interaction of p-mode oscillations with sunspots using surface-focused seismic holography. Maps of travel-time shifts, relativ…
