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…
Time-distance helioseismology: Sensitivity of f-mode travel times to flows
J. Jackiewicz, L. Gizon, A. C. Birch +1
Time-distance helioseismology has shown that f-mode travel times contain information about horizontal flows in the Sun. The purpose of this study is to provide a simple interpretat…
A procedure for the inversion of f-mode travel times for solar flows
J. Jackiewicz, L. Gizon, A. C. Birch +1
We perform a two-dimensional inversion of f-mode travel times to determine near-surface solar flows. The inversion is based on optimally localized averaging of travel times. We use…
F-mode sensitivity kernels for flows
J. Jackiewicz, L. Gizon, A. C. Birch
We compute f-mode sensitivity kernels for flows. Using a two-dimensional model, the scattered wavefield is calculated in the first Born approximation. We test the correctness of th…
Sensitivity of solar f-mode travel times to internal flows
J. Jackiewicz, L. Gizon, A. Birch
We compute f-mode travel-time sensitivity kernels for flows. Using a two-dimensional model, we show that it is important to account for several systematic effects, such as the fore…
