M1 The Crab Nebula form NOT

Post by orin stepanek » Tue Sep 20, 2005 2:34 pm

Given the fact that such an explosion is so vast; that nearby stars and their systems must be greatly affected. What kind of an affect would this have on life forms on nearby systems?

Depends upon how close another star system is to the explosion. Out here on the arm of the MW galaxy the stars are much farther apart than at the center.

It would also depend greatly on the atmospheres of the planets.

Rotating at 30 times per second; would that tend to shed matter from the surface of the neutron star?

I wouldn't have thought so, to be a neutron star there's enough gravitational energy to overcome electron degeneracy, so you'd need an extremely large amount of energy to start shedding mass...

Feel free to correct this thought people.....!

Your probably right; still, spinning at 30 revolutions per second the centrifugal force must be terrific.
