The Latest movies of Binary Neutron Star Simulations (Preliminary)


Simulation by
Wash U Neutron Star team

Visualization by
Werner Benger and the NCSA/Potsdam/Wash U and ZIB Viz teams
using Amira visualization software.


The movies on this page are for exploration of the visualization effects only.
Visualization based on preliminary simulation data.


Fully relativistic head on collision of two neutron stars.

visualized with:
red/yellow: logarithmic volumetric isolevels of epsilon (internal energy)
bluegreen: volume of rho*epsilon (energy density)
apparent horizon: created at T=63, surface indicated by dots
