This is an interesting writeup in the journal Nature (pdf. format).
quote:
From the article:
The disk resembles protoplanetary disks seen around ordinary young stars6, suggesting the possibility of planet formation around young neutron stars.
EDITED because the link does not appear to be working!
Go here and enter disk neutron star planet into the search and the article should be in the first page of articles.

It's interesting that accretion disks has been observed, with protoplanet formation.
Actually, the very first exo-planets ever discovered (by inference) were planets around pulsars. The planet's gravitational pull on the pulsar creates small but regular distortions in the pulsar's time-base.
This was in 1992.

Hmm, where did I hear that theory about a protostar and protoplanets forming from a supernova remnant? Oh ya....

Manuel says the solar system was born catastrophically out of a supernova -- a theory that goes against the widely-held belief among astrophysicists that the sun and planets were formed 4.5 billion years ago in a relatively ambiguous cloud of interstellar dust.

Right...
And how deep is the atmopsphere of a neutron star?
How strong is the magnetic field of a neutron star?
What's the density of a white dwarf? |

This is article is not about a protostar, try at least to adress the actual article and quit injecting your pseudoscience into it.

Right Dr. Mabuse , I think there was always a question how the bodies got there, and this article concludes that they formed insitu. A big point of the article is that planets may be even more common than we previously thought. |

I suppose that both of those answers would depend on the *size* of the neutron star. There tends to be a lower limit where they simply "blow" (about .189 solar masses) and an upper limit where current theory suggests that they form a black hole.

How does that idea even apply here? |

Excuse me? This is an article about how a supernova creates a disk around itself that could certainly evolve into planets. There is nothing to prevent that neutron star from forming a shell and creating a new star assuming that Manuels' theories have merit. The only thing we *don't see in these images is a hydrogen ball in the middle, but you assume stars are big hydrogen balls anyway. Talk about psuedoscience. |

Ah, peanut gallery character smears. How quaint and unexpected.  |

Oh really? How about physics? Please demonstrate how this could happen.

This is a VERY big assumption!
