Information and facts about Cepheid variable stars for a report

[Maxwells Demon]

Hello, I'm going to make a paper concerning Cepheid variable stars. I need some theory and information about these to put in the report.

It could be some history or exiting facts.. Anything..

Thanks :)

Try "cepheid stars" on google. You'll get more information than you can handle.

"You'll get more information than you can handle."

That's precisely why I'm asking here instead :P

You might want to try Wikipedia. It is highly reliable, and the chances of someone vandalizing Cephelid Binaries is very low.

I'll contribute a bit...

The stars orbit a common center of gravity and the system always contains more than one star. The center of gravity doesn't have to be another star, but a place where their gravity neutralizes each other.
