What is it about?
Binary neutron star mergers are thought to eject heavy elements as a result of rapid neutron capture reactions. Here we investigate how much fraction of ejected matter avoids neutron captures and remains free neutrons after a shock wave hits the surface of the merged object.

Why is it important?
Free neutron layers may emit significant amount of photons for the first few hours after neutron stars merge and the emission is expected to convey information on the merging event.
Perspectives
Merging of neutron stars can give us prescious information on high density matter that composed the neutron stars if we observe the electromagnetic counter parts in addition to the gravitational wave. We would like to think about phenomena associated with this event that have not been investigated.
