Non spherical Supernova Explosion?

[Nicholas Kang]

I came across books and magazines showing that supernovas aren`t happened in spherical motion, which means the heat and light aren`t detected in an equally spherical shape but there are some distorted areas. Why can this happen?

Here's a paper that discusses it more thoroughly based on direct measurements / results: http://arxiv.org/ftp/astro-ph/papers/0603/0603297.pdf.

 

This paper discusses results from simulations and some rationale for their non-spherical nature: http://arxiv.org/pdf/astro-ph/0302239.pdf.

Thanks.

Asymmetric supernovas may produce hypervelocity neutron stars traveling over 900 miles per second.

 

"...Neutron stars are the remnants of supernova explosions, and their extreme speeds are very likely the result of an asymmetric supernova explosion or the loss of their near partner during the supernova explosions that forms them. The neutron star RX J0822-4300, which was measured to move at a record speed of over 1500 km/s (0.5% c) in 2007 by the Chandra X-ray Observatory, is thought to have been produced the first way.^[15]"

Thanks again.
