Formula for neutrinos emitted per second from a Proto Neutron Star

Click For Summary
SUMMARY

This discussion focuses on developing a formula to calculate the neutrino emission from a proto-neutron star (PNS) over its lifespan of approximately 10-20 seconds. The key parameters include the total neutrinos present in the PNS, estimated at 1057, the amount of trapped neutrinos, and the neutrinos produced during cooling. Participants emphasize the importance of comparing the proposed formula with existing models in the literature, such as those addressing proto-neutron star convection and neutrino-driven winds.

PREREQUISITES
  • Understanding of proto-neutron star properties and processes
  • Familiarity with neutrino physics and emission mechanisms
  • Knowledge of mathematical modeling in astrophysics
  • Experience with scientific literature review and comparison
NEXT STEPS
  • Review the article "Proto-neutron star convection and the neutrino-driven wind: implications for the νp-process"
  • Examine "Protoneutron star evolution and the neutrino-driven wind in general relativistic neutrino radiation hydrodynamics simulations"
  • Study "Supernova Theory: Simulation and Neutrino Fluxes" for insights on neutrino transport
  • Explore mathematical modeling techniques specific to astrophysical phenomena
USEFUL FOR

Astronomers, astrophysicists, and researchers focused on supernova mechanics, neutrino physics, and mathematical modeling in stellar evolution will benefit from this discussion.

TL;DR
In need of some help fixing my formula
My current issue is trying to create a formula to find the amount of neutrinos emitted from a Proto neutron star through its life span ( which is 10-20 seconds?) currently I’ve deduced I’ll need to know the amount of total neutrinos in the PNS ( which is 10 to the 57 power ) and the amount trapped and the amount of neutrinos made during cooling. It’s for a paper I’m trying to write and I’m in the math part right now and trying to make my formula work, if anyone can help me out or push me in the right direction it would be great.

Has one compared one's formula to other models in the literature? The neutrion production and transmission will depend on assumptions of PNS properties and processes.

In the last citation:

The core collapse converts about 1.5 solar masses of
symmetric matter to a proto-neutron star about 30 km in
radius. The final neutron star has a radius of about 10 km
. . .

Convection within the proto-neutron star and mantle
clearly helps, but there is disagreement on whether this is
sufficient. Could the answer be better neutrino transport?

I thank you for the models you’ve sent, I wasn’t able to take a look at them today but I hope to tomorrow or soon. ( currently waiting on some books that’ll help me out a bit with all of this, I’ll make sure to post a response once I’ve read all the articles and gotten my books )
