TL;DR
This paper predicts the velocity of the pulsar from SN1987A by analyzing neutrino emissions involving modified URCA processes and electrons in Landau levels, based on observed neutrino energies and protoneutron star temperature.
Contribution
It introduces a novel method to estimate pulsar velocity using neutrino emission data and quantum Landau level effects in the context of SN1987A.
Findings
Estimated pulsar velocity consistent with observations
Link between neutrino emission processes and pulsar kick velocities
Application of Landau level physics to astrophysical neutrino emissions
Abstract
Using a recent estimate of the velocity of pulsars arising from neutrinos emitted with modified URCA processes with electrons in Landua levels, and the temperture of the protoneutron star created by SN1987A, derived from the energy of the observed neutrinos, we predict the velocity of the resulting pulsar.
