Uncovering the Hidden Layers of the Sunve allowed us to determine the structure of the inner layers of the Sun. This in turn has led to tests of solar models, and perhaps more importantly, tests of the properties of stellar material. I review some of the interesting results that helioseismic structure inversions have revealed and how tod

Solar Rotationt challenged modellers—such as the nearly-radial profile of the lines of constant rotation in the convection zone, the thin shear layer or tachocline at its base, and the nearly-rigid rotation in the radiative interior. This review will highlight Michael Thompson’s important contributions to techniq

Time-Distance Helioseismology of Deep Meridional CirculationTime-distance helioseismic studies of the deep structure of MC, however, have yielded conflicting inferences. Here, following a summary of existing results we show how a large center-to-limb systematics (CLS) in the measured travel times of acoustic waves affects the inferences through an analysis o

Surface Rotation and Magnetic Activity of Solar-Like Stars: Impact on Seismic Detectionsrather easily. Here we show the result of the measurement of rotation periods for a large number of . solar-like stars along with their level of magnetic activity. We also study solar-like stars for which oscillations have not been detected using 1 month of . data in order to understand what can be

New Inversion Scheme for Time-Distance Helioseismology4). Optimization procedures that rely on matrix inversions may suffer from numerical instabilities caused by ill-conditioned matrices. Markov Chain Monte Carlo (MCMC) methods sample the parameter space, independent of its complexity, while Bayesian methods are powerful ways of of understanding the p
