Question on neutrino emission machanism in neutron star

Click For Summary
SUMMARY

The discussion focuses on the mechanisms of neutrino emission responsible for the cooling of neutron stars. Key mechanisms include the direct Urca process and the emission from Cooper pairs, with the latter being highlighted as a superior alternative. The paper titled "Neutrino Emission from Cooper Pairs and Minimal Cooling of Neutron Stars" provides a comprehensive overview of these processes, particularly in chapters 56-61. The emissivity calculations for each mechanism are essential for understanding the cooling rates of neutron stars.

PREREQUISITES
  • Understanding of neutron star physics
  • Familiarity with neutrino emission mechanisms
  • Knowledge of the direct Urca process
  • Basic grasp of stellar cooling theories
NEXT STEPS
  • Read the paper "Neutrino Emission from Cooper Pairs and Minimal Cooling of Neutron Stars"
  • Study the direct Urca process in detail
  • Explore the equations for calculating emissivity in neutron stars
  • Investigate other cooling mechanisms in neutron stars
USEFUL FOR

Astronomers, astrophysicists, and researchers studying neutron star cooling processes and neutrino emissions will benefit from this discussion.

How many neutrino emission mechanism, that causes the cooling of star, are there in neutron star?

And How, what equation, to calculate the emissivity of each mechanism?

The direct urca process is not very satisfactory, imo. This appears a better alternative.
