Astronomers have discovered the most massive neutron star ever observed. It's 15 miles across with a mass of more than twice the sun.
Neutron stars are created when massive stars reach the ends of their lives and are composed of the densest matter in the known universe.
How can this happen? __5__The theory is that some stars explode when their density increases to a particular point; they “collapse” and sometimes a supernova occurs. The collapse of a star may produce a “White Dwarf” of a “neutronstar”—a star which matter is so dense that if ...

A star begins as a cloud of interstellar gas, mostly made of hydrogen. Eventually, small density differentials begin to make...

Using the largest well-measured neutron star mass, 1.97 M$_\odot$, it is possible to show that the energy density can never exceed about 2 GeV, the pressure about 1.3 GeV, and the baryon chemical potential about 2.1 GeV. Further, if quark matter comprises a significant component of ...

The theory is that some stars explode ,when their density increases to a particular point; they "collapse" and sometimes a supernova (超新星) occurs. The collapse of a star may produce a "White Dwarf (白矮星) " or a "neutron star"-- a star whose matter is so dense that it continual...
According to the Hugenholtz-Van Hove theorem, nuclear symmetry energy \esym and its slope \lr at an arbitrary density $ho$ are determined by the nucleon isovector (symmetry) potential \usym and its momentum dependence $\frac{\partial U_{sym}}{\partial k}$. The latter determines uniquely ...
