True that

I wonder if they're all 'vampiric' like Mira. That would be interesting to know.

**VAMPIRES IN SPACE!!!**

Methinks that they are but that is just a gut feeling

Like anything else we are not sure about we'll have some that say yes and some that will say definitely not....

But it would be fun to see how the sides match up

The answer is: There are two different kinds.

There are Intrinsic Variable Stars where the star itself actually varies in brightness as it is.

Then there are Extrinsic Variable Stars that are eclipsed by an orbiting companion every so often

Seconded

Those variable stars are pretty cool. Now I actually understand what one is after watching that.

Not all variable stars are binaries. Our own star, Sol is a variable star. It has a short cycle of variance that is about 11 years from minimum to minimum, and a longer cycle that varies at different rates, from perhaps a couple hundred years to a millennium or two.


Edit:
Our star would be the intrinsic variable star.

Speaking of Stars.....I thought this was super duper and easy to follow yet still mind boggling.  Amazing
