Neutron stars are outstanding corpses no more than 10km or 20km across. It appears rather a common occurence for neutron stars to orbit in binary systems and as they do, slowly eek away energy in the form of gravity waves. Artists conception of a neutron star merger.
Neutron stars are stellar remains no more than 10km or 20km across. To put this into context, under the gravitational collapse, all the area in between the parts of atomic nuclei is squeezed out producing a gigantic neutron a number of kilometres throughout!

It seems quite a common occurence for neutron stars to orbit in double stars and as they do, gradually eek away energy in the form of gravity waves. These waves resemble those on the ocean rather propagate through the fabric of space-time. Ultimately, adequate energy is lost that the neutron stars collide and it is this that has allowed groups of astronomers to study the processes throughout some of the most extreme conditions discovered in the Universe..
An international team that involved the Max Planck Institute for Gravitational Physics and the University of Potsdam have actually utilized a brand-new software tool to mimic the physical processes from neutron star mergers (otherwise known as a kilonova). The group also used X-ray observations, radio signals, nuclear physics computations and even information from Earth based accelerators and for the first time plugged the entire lot into the simulations..
On 17 August the LIGO/Virgo team detected 2 neutron stars clashing in an elliptical galaxy in Hydra. The crash was identiifed from gravitational wave and gamma ray observations and by studying such high energy collisions we can find out more about the formation of heavy elements at severe pressures and densities far higher than discovered in atomic nuclei.

The results were extremely appealing with the forecasts from the model matching observation. Now the team are running further observations with gravitational wave detectors as they hunt down the next neutron star merger to utilize the tool again and further improve its model.

There are numerous mysteries worldwide of astronomy and a fair number relate to the processes throughout completion of the life of an incredibly massive star. Throw in the complexity of accidents and you have a genuine head scratching issue on your hands. In 2017 clashing neutron stars were detected and the data has enabled a brand-new simulation to be tested with forecasts beautifully matching observation.
In 2017 clashing neutron stars were identified and the information has permitted a brand-new simulation to be evaluated with predictions magnificently matching observation.
