Any stars in the universe can collide, whether they are "alive", meaning fusion is still active in the star, or "dead", with fusion no longer taking place. White dwarf stars, neutron stars , black holes , main sequence stars , giant stars , and supergiants are very different in type, mass, temperature, and radius, and accordingly produce ...
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 Tolman–Oppenheimer–Volkoff limit—a black hole.
This artist's impression shows a kilonova produced by two colliding neutron stars. On October 16, 2017, the LIGO and Virgo collaborations announced the first detection of a gravitational wave ( GW170817 [ 9 ] ) which would correspond with electromagnetic observations, and demonstrated that the source was a binary neutron star merger . [ 10 ]
Recently, researchers from the University of Copenhagen re-analyzed data from the first-ever detected kilonova—a massive explosion that occurs when two neutron stars collide, merge, and collapse ...
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]
For the first time ever, humans have observed light and gravitational waves from a neutron star collision 130 million light years away. For the first time ever, humans have observed light and ...
The origin and properties (masses and spins) of a double neutron star system like GW170817 are the result of a long sequence of complex binary star interactions. [41] The gravitational wave signal indicated that it was produced by the collision of two neutron stars [9] [18] [20] [42] with a total mass of 2.82 +0.47 −0.09 solar masses (M ☉). [2]
The favored hypothesis for the origin of most short gamma-ray bursts is the merger of a binary system consisting of two neutron stars. According to this model, the two stars in a binary slowly spiral towards each other because gravitational radiation releases energy [123] [124] until tidal forces suddenly rip the neutron stars apart and they ...
