Team records 'music' from stars

[Ichingcarpenter]

There are 4 separate MP3 songs or tracks you can listen to at the link
from different stars, star clusters and our sun.

Scientists have recorded the sound of three stars similar to our Sun using France's Corot space telescope.
A team writing in Science journal says the sounds have enabled them to get information about processes deep within stars for the first time.

If you listen closely to the sounds of each star - by clicking on the media in this page - you'll hear a regular repeating pattern.

These indicate that the entire star is pulsating.

You'll also note that the sound of one star is very slightly different to the other. That's because the sound they make depends on their age, size and chemical composition.

Sounds like a 50s Sci/Fi movie.

1. The Jefferson Airplane can't hold a candle by comparison...

[Ichingcarpenter]

3. I was reminded by some of the soundtracks from "Forbidden Planet"

Anyway pretty cool.

12. Also 2001: A Space Odyssey big time. nt

[NOW tense]

2. All things are vibrational.

Everything including our thoughts.

5. Pythagoras and the music or harmony of the spheres

Came to mind:

4. Cool.

Think I'll do something with globular cluster and HD 49933.

6. Anyone know how I can put these in GarageBand or iTunes?

I'd like to send these to my daughter who is a musician and also
play around with them myself.

8. Here are the individual wav files:

http://greyleonard.com/du/HD49933.wav
http://greyleonard.com/du/HD181420.wav

I've never used GarageBand, but I imagine you'd just need to put these wavs into a directory that GB searches for samples.

10. Thanks it worked great

How did you get the wave file?

[greyl]

11. Cool again.

While playing them sequentially in the browser, I recorded them into one file with SoundForge. Then I separated them.

7. You need to click "play" on each at the same time.

9. Not another Britney Spears thread....!

ugh...

13. The GONG network has been doing this for a while

The Beat Goes On - Inside The Sun

"Astronomers from the National Science Foundation's National Solar Observatory are announcing in today's issue of Science that their discovery of periodically varying gas motions below the solar surface provides an important clue toward solving the biggest secret of the Sun - the origin of the 11-year cycle of solar activity.

Lead author Rachel Howe, with Frank Hill and Rudi Komm from the National Solar Observatory (NSO) in Tucson, AZ, and colleagues from other institutions, have analyzed 4.5 years worth of observations from the National Science Foundation's Global Oscillation Network Group (GONG), a world-wide network of telescopes providing continuous observations of the Sun, to make this intriguing discovery.

Howe and colleagues have discovered variations in the motion of a region far below the solar surface possibly connected to the solar activity seen on the surface. Probing the depths of the solar interior with a technique known as "helioseismology" which uses sound waves trapped inside the Sun, Howe and her colleagues are able to measure the speed of the gas at different locations below the surface. They then searched for organized, systematic changes in the speed of the moving material. They found that near the base of the convective layer, approximately 30% of the Solar radius or 210,000 km beneath the surface, the rotation rate periodically varies with a cycle of 15 months. Their systematic search looked from the solar surface to nearly half way to the solar core, and from the solar equator to near the pole."

14. I was watching a show about the aurora on the Science Channel

And, the aurora puts out a sort of haunting sound. Very cool.
