Inferring solar differential rotation through normal-mode coupling using Bayesian statistics
Samarth G. Kashyap, Srijan Bharati Das, Shravan M. Hanasoge +2
Normal-mode helioseismic data analysis uses observed solar oscillation spectra to infer perturbations in the solar interior due to global and local-scale flows and structural asphe…
Sensitivity kernels for inferring Lorentz stresses from normal-mode frequency splittings in the Sun
Srijan Bharati Das, Tuneer Chakraborty, Shravan M. Hanasoge +1
Departures from standard spherically symmetric solar models, in the form of perturbations such as global and local-scale flows and structural asphericities, result in the splitting…
A spectral-infinite-element solution of Poisson's equation: an application to self gravity
Hom Nath Gharti, Jeroen Tromp
We solve Poisson's equation by combining a spectral-element method with a mapped infinite-element method. We focus on problems in geostatics and geodynamics, where Earth's gravitat…
Double-difference adjoint seismic tomography
Yanhua O. Yuan, Frederik J. Simons, Jeroen Tromp
We introduce a `double-difference' method for the inversion for seismic wavespeed structure based on adjoint tomography. Differences between seismic observations and model predicti…
Anelastic sensitivity kernels with parsimonious storage for adjoint tomography and full waveform inversion
Dimitri Komatitsch, Zhinan Xie, Ebru Bozdag +4
We introduce a technique to compute exact anelastic sensitivity kernels in the time domain using parsimonious disk storage. The method is based on a reordering of the time loop of…
