Are novae considered intrinsic, extrinsic, periodic or non-periodic? According to my textbook - Longman physics - they're periodic and extrinsic, but the csu website says they're non-periodic, which has got me all confused now. Which is right?

It got my teacher confused too cos he thought they were non-periodic. He sat there for 5 mins staring at the textbook and couldnt come to any conclusion. Eventually he's just like, look it up on the net and see what you find.

Hmm...I'm pretty sure novae are non-periodic and intrinsic. I don't know why your textbook would say they're periodic. Maybe I'm totally wrong and don't realise it lol
Because a novae's brightness is pretty irregular, this would go under the definition of non-periodic.

The reason I would think they'd be non-periodic is because they're intrinsic. GENERALLY extrinsic stars are periodic.

OK, have a look at Wikipedia (sometimes the answer to most problems).
ttp://en.wikipedia.org/wiki/Nova

They mention that re-current novae are rare but do occur. Then they postulate that perhaps all novae are re-current but on a time frame that is much longer than current records.

So, there you go.
