Hi all(adsbygoogle = window.adsbygoogle || []).push({});

I'd like to know your opinion about this: how to evaluate if an autogravitating body is stable? I'd like to know which analytic consideration should we do.

Example: experience tells us that a sphere is pretty stable. But... something else? A torus is stable? Or should it evolve into something different, maybe a thin ring? How to evaluate this, in a mathematical view?

(Obviously I suppose there are differences if the body is rigid or not.)

Thank you

Wedge!

PS I hope it's not too complicated (I'm at the first year of University...)
