It can happen. Very unlikely, but it can.

Gotcha.

I understand your questioning of Weber's decision. I don't get it
myself.
I'm sure Weber had some mad scheme in mind when he came up with this (or
it was a result of poor understanding of stellar physics, don't know)

Bingo!

If you need help finding stuff, let me know. I can always go through
my stack of books for stuff (barring that, there's a library
upstairs...)
