Helioseismology [PDF]

Journal of Astrophysics and Astronomy, 2005
The sun being the nearest star, seismic observations with high spatial resolution are possible, thus providing accurate measurement of frequencies of about half million modes of solar oscillations covering a wide range of degree.

Outstanding problems in local helioseismology

Astronomische Nachrichten, 2007
Time‐distance helioseismology and related techniques show great promise for probing the structure and dynamics of the subphotospheric layers of the Sun. Indeed time‐distance helioseismology has already been applied to make inferences about structures and

Image compression in local helioseismology

Astronomy and Astrophysics, 2014
Context. Several upcoming helioseismology space missions are very limited in telemetry and will have to perform extensive data compression. This requires the development of new methods of data compression. Aims.

Helioseismology with Solar Orbiter

Space Science Reviews, 2014
The Solar Orbiter mission, to be launched in July 2017, will carry a suite of remote sensing and in-situ instruments, including the Polarimetric and Helioseismic Imager (PHI).

Local helioseismology using ring diagram analysis

Astronomische Nachrichten, 2007
Ring diagram analysis is an extension of global helioseismology that is applied to small areas on the Sun. It can be used to infer the horizontal components of large scale flows as well as the structure, and variations thereof, in the outer convection ...
