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…
Helioseismic Holography of Simulated Solar Convection and Prospects for the Detection of Small-Scale Subsurface Flows
D. C. Braun, A. C. Birch, D. Benson +2
We perform helioseismic holography on realistic solar convection simulations and compare the observed travel-time perturbations with the expected travel times from the horizontal f…
Sensitivity of time-distance helioseismic measurements to spatial variation of oscillation amplitudes I. Observations and a numerical model
S. P. Rajaguru, A. C. Birch, T. L. Duvall +2
It is well known that the observed amplitude of solar oscillations is lower in sunspots than in quiet regions of the Sun. We show that this local reduction in oscillation amplitude…
