Hmm. A farfale phase? (butterflies) Perhaps a chonchiglie phase? Made of the hardest substance in the universe? Mmm - tasty.
Thanks - I knew neutron stars had some kind of "atmosphere", but I didn't realise they had layers and interlayers.
[Edit] I didn't even realise that NSs had protons in them. I thought protons all degenerated into electrons and neutrons. I have new stuff to learn about - I knew NSs were about the weirdest places anywhere, but they're weirder than I thought.
