The methods consist essentially of approximating the neutron densities at each velocity by fundamental mode shapes for each velocity . ")
2.
This occurs in environments with a high neutron density, possibly in a supernova or during the merger of two neutron stars.
3.
It had a neutron density 10 million times greater than a supernova _ " more impressive in that respect, " a scientist observer said, " than a star ."
4.
As we go deeper into the neutron star the free neutron density increases, and as the Fermi momentum increases with increasing density, the Fermi energy increases, so that energy levels lower than the top level reach neutron drip and more and more neutrons drip out of nuclei so that we get nuclei in a neutron fluid.
