A neutron star merger is the stellar collision of neutron stars. When two neutron stars fall into mutual orbit, they gradually spiral inward due to the loss of energy emitted as gravitational radiation. [1] When they finally meet, their merger leads to the formation of either a more massive neutron star, or—if the mass of the remnant exceeds ...
The first identification of r-process elements in a neutron star merger was obtained during a re-analysis of GW170817 spectra. [77] The spectra provided direct proof of strontium production during a neutron star merger. This also provided the most direct proof that neutron stars are made of neutron-rich matter.
When two neutron stars orbit each other closely, they spiral inward as time passes due to gravitational radiation. When they meet, their merger leads to the formation of either a heavier neutron star or a black hole, depending on whether the mass of the remnant exceeds the Tolman–Oppenheimer–Volkoff limit. This creates a magnetic field that ...
Scientists just got to watch nearly the entirety of a kilonova explosion caused by a neutron star merger, thanks to a multi-national telescopic effort.
The gravitational wave signal matched prediction for the merger of two neutron stars, two seconds before the gamma-ray burst. The gravitational wave signal, which had a duration of about 100 seconds, was the first gravitational wave detection of the merger of two neutron stars. [1] [19] [20] [21] [22]
Two astronomers think they've pinpointed the ancient stellar collision that gave our solar system its cache of precious gold and platinum -- some of it, anyway.In a new study published May 1 in ...
In July 2019, astronomers reported that a new method to determine the Hubble constant, and resolve the discrepancy of earlier methods, has been proposed based on the mergers of pairs of neutron stars, following the detection of the neutron star merger of GW170817. [108] [109] Their measurement of the Hubble constant is 70.3 +5.3 −5.0 (km/s ...
GRB 230307A was an extremely bright, long duration gamma-ray burst (GRB), likely produced as a consequence of a neutron star merger or black hole - neutron star merger event.
