Abstract:  Helioseismology and Helioseismic Inversion Helioseismology studies the structure and dynamics of the Sun’s interior by observing oscillations on the surface. In recent years, helioseismology has made substantial progress towards the understanding of the physics of solar oscillations and the physical processes inside the Sun. In addition, a new field called local helioseismology has been developed which studies oscillation travel times and its aim is to address fundamental questions in time-distance helioseismology, such as the choice of travel-time measurements and the sensitivity kernels for inversions, to probe the complex structures like convective flows. The choice of regularization method and considering computational cost in terms of number of observations are key factors in helioseismic inversions.
