Minuscule corrections to near-surface solar internal rotation using mode-coupling

Srijan Bharati Das, Samarth G. Kashyap, Deniz Oktay +2

The observed solar oscillation spectrum is influenced by internal perturbations such as flows and structural asphericities. These features induce splitting of characteristic freque…

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…

Full Waveform Inversion for Time-Distance Helioseismology

Shravan Hanasoge, Jeroen Tromp

Inferring interior properties of the Sun from photospheric measurements of the seismic wavefield constitutes the helioseismic inverse problem. Deviations in seismic measurements (s…

Seismic probes of solar interior magnetic structure

Shravan Hanasoge, Aaron Birch, Laurent Gizon +1

Sunspots are prominent manifestations of solar magnetoconvection and imaging their subsurface structure is an outstanding problem of wide physical importance. Travel times of seism…

The Adjoint Method Applied to Time-Distance Helioseismology

Shravan Hanasoge, Aaron Birch, Laurent Gizon +1

For a given {\it misfit function}, a specified optimality measure of a model, its gradient describes the manner in which one may alter properties of the system to march towards a s…
