The densest object in the universe is the neutron star. The stars are mostly made of neutrons. We don't know much about the matter produced during the collision of two stars. A model that gives insights about matter under extreme conditions has been developed by scientists from the Asia Pacific Center for Theoretical Physics.
A small object called a neutron star can be formed after a massive star explodes as a supernova. To get the density inside a nova, one needs to squeeze a huge body like our sun down to the size of a city. For the first time, the ripples in spacetime that are caused by a collision of two stars could be measured here on Earth.
The composition of the merging product is not known. quarks, which are trapped in neutrons, can appear in free form after a collision A new model that allows them to get one has been developed by Dr. Christian Ecker and Dr. Matti Jrvinen.
Nuclear physics models can be used to describe the transition to dense and hot quark matter, but not at high densities. The phase transition between dense nuclear and quark matter can be described using a mathematical relationship found in string theory.
The simulations were implemented in collaboration with Samuel Tootle and Konrad Topolski.
The researchers want to compare their simulations with future waves measured from space in order to learn more about quark matter.
