A low-mass black hole and a neutron star merge to a black hole surrounded by an accretion disk

Показать описание
When a black hole (black sphere) and a neutron star (red sphere) merge, matter is ejected and forms an accretion disk surrounding the resulting black hole. The simulation shows the density of the ejected matter with colors ranging from blue (lower density), green, yellow to red (higher density).

Wow, in less than 0.2 of a second a little neutron star has its breakfast spilt a few hundred kilometres all around the place because it wasn't watching where it was walking.

Quick question, is there any understanding of what that disc material is composed of after it gets sprayed around like that? I mean is there any other nuclear reactions or changes in the material that affect modelling like this? Purely out of interest is all.

If either the Blackhole or Neutron Star had significant magnetic fields associated with them would that have influenced the possibility of jets forming during this collision?
