Neutron stars are the densest objects in our universe, except for black holes. As their name suggests, neutron stars are mainly made of neutrons. However, our knowledge about the matter produced during the collision of two neutron stars is still limited. Scientists from Goethe University Frankfurt and the Asia Pacific Center for Theoretical Physics in ...
An international research team has for the first time combined data from heavy-ion experiments, gravitational-wave measurements, and other astronomical observations using advanced theoretical modeling to more precisely constrain the properties of nuclear matter as it can be found in the interior of neutron stars. The results were published in the journal Nature. Throughout the Universe, ...
When two neutron stars spiral into one another and merge to form a black hole — an event recorded in 2017 by gravitational wave detectors and telescopes worldwide — does it immediately become a black hole? Or does it take a while to spin down before gravitationally collapsing past the event horizon into a black ...
Gravitational-wave researchers at the University of Birmingham have developed a new model that promises to yield fresh insights into the structure and composition of neutron stars. The model shows that vibrations, or oscillations, inside the stars can be directly measured from the gravitational-wave signal alone. This is because neutron stars will become deformed under the ...
New images from ESO’s Very Large Telescope in Chile and other telescopes reveal a rich landscape of stars and glowing clouds of gas in one of our closest neighboring galaxies, the Small Magellanic Cloud, including a dead star circled by light. The pictures have allowed astronomers to identify an elusive dead star buried among filaments ...
