Is it possible to unbind a neutron star?

Click For Summary
SUMMARY

Neutron stars can indeed be unbound through specific astrophysical events, particularly during neutron star mergers. When two neutron stars collide, a significant portion of the matter is absorbed into a larger neutron star or black hole, while a small fraction, estimated at a few percent, is expelled into space. This expelled matter can expand and transform into regular matter, contributing to the formation of heavy elements in the universe, particularly those heavier than iron. The phenomenon is crucial for understanding cosmic element synthesis.

PREREQUISITES
  • Understanding of neutron star physics
  • Familiarity with supernova mechanisms, specifically Type Ia supernovae
  • Knowledge of black hole dynamics and tidal disruption events
  • Basic concepts of nucleosynthesis in astrophysics
NEXT STEPS
  • Research neutron star merger dynamics and their implications for heavy element formation
  • Explore the role of black holes in tidal disruption events
  • Study nucleosynthesis processes in supernovae and neutron star collisions
  • Investigate the observational evidence for neutron star mergers and their outcomes
USEFUL FOR

Astronomers, astrophysicists, and students interested in stellar evolution, cosmic element formation, and the dynamics of extreme astrophysical events.

TL;DR
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.
