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…
Scattering of acoustic waves by a magnetic cylinder
L. Gizon, L., S. M. Hanasoge +1
With the aim of studying magnetic effects in time-distance helioseismology, we use the first-order Born approximation to compute the scattering of acoustic plane waves by a magneti…
High-resolution mapping of flows in the solar interior: Fully consistent OLA inversion of helioseismic travel times
J. Jackiewicz, L. Gizon, A. C. Birch
To recover the flow information encoded in travel-time data of time-distance helioseismology, accurate forward modeling and a robust inversion of the travel times are required. We…
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…
