SN1987A: Temporal Models

TL;DR

This paper explores how the trajectories of massless spinning particles like photons, neutrinos, and gravitons emitted during supernovae are spin-dependent, affecting the information they carry and their detection timing.

Contribution

It introduces a spin-dependent model for particle trajectories in supernova events, contrasting it with the traditional spin-independent approach.

Findings

Trajectories of particles are influenced by their spin.

The spin-dependent model differs from conventional models in predicted arrival times.

Implications for interpreting supernova signals and astrophysical information.

Abstract

It is well known that carriers of astrophysical information are massless spinning particles. These carriers are photons, neutrinos and, expectedly, gravitons. All these particles are emitted during supernova events. Information carried by these particles characterize their sources, but such information are affected by the trajectories of the carriers. Recently, it is shown that these trajectories are spin dependent. Knowing these trajectories and the arrival times of such particles to the detectors, a spin dependent model is constructed and compared with the conventional spin independent model.
