I have questions about Unstable stars.

I haven't yet had a star naturally explode on me yet, but in one of my current games, 5 of my systems have unstable stars.

I checked stellarabilities.txt and the other appropriate .txt data files to try to figure out what determining factors play a part in unstable stars exploding.

So far as I can see, the unstable star sector types have a 0% chance of exploding, as set in stellarabilities.txt. But some of you say that you have had stars explode on you before.

So, what is determining when stars explode naturally?
