Hi,


I'm an artist but very interested in science as an input to my work. I wonder if someone can help me? Is there some publicly available resource that would contain readings of any signals from the Star Antares?
I am writing some music about the Red Giant, and would like to somehow incorporate some hard data into the composition.


Any assistance to point me in the right direction would be really appreciated.


Cheers.

well, I will jump in here - others please correct me if I am wrong.

The only signals we receive from the star Antares are light signals. This light can be analysed by astronomers, but would not yield sound information that you seek. I do not believe Antares is a radio source of any note, so no help to you there with any "noise" from that part of the spectrum.

Have you considered the name Antares and its meaning "rival to Mars"? any music on record about Mars may give you something to go on.

regards
John

I assume you are after a real time radio signal?

Sorry I can't help you there, but what about a spectrum of Antares? I have attached one I captured in 2009. The horizontal axis is wavelength in Angstroms, the vertical axis is intensity. If you could extract the data in number form you could translate wavelength to frequency (in the audible range) and generate a tone characteristic of Antares.

"The chances of anything coming from Antares, are a trillion to one", he said ... "The chances of anything coming from Antares, are a gizillion to one, but still....."
Sorry, couldn't resist :D

I think he might be looking for oscillating patterns, like mentioned here (http://www.researchgate.net/publication/241711398_Pattern_formation_in_rapi dly_oscillating_peculiar_A_stars). I can't remember the correct name for it, but stars oscillate in their own patterns and you can turn this pattern into a "note" They have a naturally very long wavelength, and for us to "hear" them they have to artificially amplified. There was an astronomer who did a tour of Australia talking about this some years ago, called "The music of the stars" or something like that. It was a while ago, so I'm really scraping in the corners of my memory on this, hope it makes sense. If someone can remember the name better a search might turn up better results.

Edit: Found it! Stellar seismology! Here is a Youtube vid (https://www.youtube.com/watch?v=h7TfNrIBKGI) on it. Another link here (http://www.world-science.net/othernews/060809_spheres.htm). The term to use in Wikipedia is Asteroseismology (https://en.wikipedia.org/wiki/Asteroseismology). I can't see any specific mention of Antares, you'll have to dig for this yourself.

Just make it up, lol. I mean, who would know? And would it actually make a scrap of difference to your audience?

Seriously though, your own imaginative interpretation of a 'possibility' could be a whole lot more interesting than the reality!

Anyway, just my two bobs worth

Another approach - use an image of Antares to generate music data you may be able to incorporate......
