Question from the week before:

What star is most commonly referred to as the Demon Star?

Answer:

The star Algol in the constellation Perseus is called the Demon Star. Its name means head of the ghoul or ogre in Arabic.

The first eclipsing binary in Perseus was found,
That changed in brightness often as its stars went round and round.
It's called an occultation when they circumnavigate
Around their common center as Algol will demon-strate!
