I Is it possible to unbind a neutron star?

AI Thread Summary
Neutron stars can theoretically be unbound through high-speed collisions or tidal disruptions, particularly during neutron star mergers. While most matter from such events is absorbed into a larger neutron star or black hole, a small fraction is expelled into space, transforming into regular matter. This process is believed to be a significant source of heavy elements in the universe, particularly those heavier than iron. The discussion highlights the potential for neutron stars to contribute to the cosmic matter cycle. Further exploration of neutron star mergers can provide deeper insights into these phenomena.

TL;DR Summary
Unbinding a neutron star
Type 1a supernovas unbind a white dwarf. Is there some theoretically possible scenario in which a neutron star could be unbound and thus turned into degenerate matter or even regular matter? For example, by a high speed glancing collision with another neutron star or by tidal disruption by a black hole?

Yes! This is exactly what can happen when two neutron stars merge. Most of the matter is incorporated into a larger neutron star or black hole, but some small fraction (a few % ?) gets flung out into space, where it expands and becomes regular matter. We think this is the source of most of the heavy elements (heavier than iron) in our universe. Here's a starting point for further reading:

Thanks for that answer, phyzguy! I was hoping something along those lines could occur.
 
TL;DR Summary: In 3 years, the Square Kilometre Array (SKA) telescope (or rather, a system of telescopes) should be put into operation. In case of failure to detect alien signals, it will further expand the radius of the so-called silence (or rather, radio silence) of the Universe. Is there any sense in this or is blissful ignorance better? In 3 years, the Square Kilometre Array (SKA) telescope (or rather, a system of telescopes) should be put into operation.

Thread 'Could gamma-ray bursts have an intragalactic origin?'
This is indirectly evidenced by a map of the distribution of gamma-ray bursts in the night sky, made in the form of an elongated globe. And also the weakening of gamma radiation by the disk and the center of the Milky Way, which leads to anisotropy in the possibilities of observing gamma-ray bursts. My line of reasoning is as follows: 1. Gamma radiation should be absorbed to some extent by dust and other components of the interstellar medium. As a result, with an extragalactic origin, fewer...
