The red giant released a sufficiently dense slow wind to feed its neutron star companion, giving rise to high-energy emission from the dead stellar core for the first time.
The gravity of neutron stars pulls surrounding material from companion stars onto them and, as this material falls towards the neutron star, it heats up and glows with X-rays.
If one binary neutron star would coalesce in 300 million years, others might do so tomorrow--and the energetic burst of gravitational waves the collision produced should be detectable with extremely sensitive instruments here on Earth.
For the first time scientists have observed gravitational waves and light coming from two neutron stars colliding in a nearby galaxy.
Washington, Oct 18 (ONA) An international team of astronomers detected the first gravitational waves from merging neutron stars, and found proof they are the source of the universe's heavy elements, including gold and platinum, the Live Science website said.
A neutron star typically would have a mass that's perhaps half a million times the mass of the Earth, but they're only about 20 kilometers across (about the size of London).
But the neutron star collisions don't appear to happen often enough to account for all the metal.
After the mantle explodes out of the super nova, the core is left as a neutron star and starts to oscillate about its equilibrium of gravity and pressure.
Thorne-Zytkow objects (TZOs) are hybrids of red supergiant and neutron stars that superficially resemble normal red supergiants, such as Betelguese in the constellation Orion.
Now it appears that neutron star mergers inevitably produce aligned jet-like structures in an ultrastrong magnetic field.
Astronomers using the National Science Foundation's Green Bank Telescope (GBT) have discovered the most massive neutron star yet found, a discovery with strong and wide-ranging impacts across several fields of physics and astrophysics.
Papers from a summer 2003 symposium reflect recent research in neutron star properties made possible by the Chandra X-Ray Observatory and the XMM-Newton mission.
Theory predicts this could be a neutron star -one teaspoonful of which weighs a billion tons -or a black hole, which is so dense nothing can escape its gravity, not even light.
A group of researchers in Japan said Sunday it has succeeded in creating super-dense conditions comparable to that inside a neutron star, or a density several quadrillion times that of water.
The object, travelling more than 100 times faster than a supersonic jet, is not an asteroid or comet but something far stranger - a runaway neutron star, astronomers revealed today.
