Local Helioseismology Analyses with Hinode/SOT Datasets

Chapter
Part of the Astrophysics and Space Science Library book series (ASSL, volume 449)

Abstract

The solar internal structure and dynamics have been probed by examining the oscillations of the Sun, or by “listening to the Sun”; helioseismology provides us with unique tools for these analyses. Starting from a brief introduction on local helioseismology, in this article I will describe what were our goals and what has been achieved, in learning from the local helioseismology analyses using observations by the Solar Optical Telescope aboard Hinode. This includes the detection of helioseismic signatures of flows in the solar atmosphere, study of supergranular cell structures in the solar polar regions, and sunspot seismology.

Keywords

Sun: helioseismology Sun: oscillations
