Sentences with word «helioseismology»

Across San Francisco Bay from Lin, a group of scientists at Stanford University is looking at the sun's interior through a remarkable technique called helioseismology.

With helioseismology data, which track acoustic oscillations on the sun, researchers can follow the development of the jet stream thousands of kilometers below the sun's surface, potentially allowing for better forecasts of the timing of the solar cycle.

A third scientist used helioseismology to look at minima in acoustic oscillations that often correspond with sunspot minima.

With helioseismology data, which track acoustic oscillations on the sun, researchers can check in on the progress of the jet stream at depths of roughly 1,000 kilometers, potentially allowing for better forecasts of the timing of the solar cycle.

However, just as seismology uses waves generated by earthquakes to reveal the interior structure of the Earth, the discipline of helioseismology makes use of pressure waves traversing the Sun's interior to measure and visualize the Sun's inner structure.

The answer comes from helioseismology, an approach employed by the Michelson Doppler Imager (MDI) on the Solar and Heliospheric Observatory (SOHO) satellite.

Using the technique of time - distance helioseismology, three planes are shown.

He and colleague Rachel Howe have been tracking the solar jet streams since the mid-1990s using a technique called helioseismology.

The University of Birmingham is one of the pioneers in the field of helioseismology and researchers have been using the Birmingham Solar Oscillations Network (BiSON) to study the Sun through sound waves since 1985.

Currently, the only way to measure anything below the solar surface is with helioseismology, which studies changes in sound waves as they travel through the solar interior just as seismology is used in geophysics to study the Earth's interior.

A 60 - foot solar tower nearby is dedicated to helioseismology — the study of the sun's oscillations in order to determine its internal dynamics.)

Hill's NSO colleague Sushanta Tripathy also turned to helioseismology to investigate the recent solar minimum, finding that in acoustic oscillations deep within the sun there were in fact two separate minima — one in late 2007 that did not correspond to the sunspot minimum, and one around late 2008 that did.

Prof Yvonne Elsworth, of the School of Physics and Astronomy at the University of Birmingham, explains: «The Sun is very much like a musical instrument except that its typical notes are at a very low frequency — some 100,000 times lower than middle C. Studying these sound waves, using a technique called helioseismology, enables us to find out what's going on throughout the Sun's interior.»

This is called helioseismology, and as the name suggests, it is similar to the concept of studying subterranean waves on Earth to predict earthquakes.
