dear friends,
everything in it's purest form is energy and energy vibrates...

star vibrations have allowed scientists to make the first direct measurement
of a star's age.
and they've opened the door to stellar laboratories that will help us understand
more about processes that are difficult to study on earth.
australian astrophysicist, associate professor tim bedding of the university of
sydney, and team will report their research in the august issue of the
astrophysical journal.
most stars including the sun pulse continuously due to the violent mixing of
gases in their outer layers, says bedding.
he has described the how a nearby star in our galaxy pulsates by studying the
doppler shift of light waves coming off the star's surface.
and he has developed computer models to show how complex the pulsation is.
"it doesn't just vibrate simply in and out. it vibrates in lots of different
modes simultaneously," says bedding (see animated images).
in the same way that geologists use seismology to study the interior of the
earth, bedding is using asteroseismology, the study of these vibrations or 'star
quakes', to find out more about stars.
in this case, he was interested in seeing whether he could confirm what was
already known about the composition, mass and age of the star.
