Sites That Can Produce Left-Handed Amino Acids in the Supernova Neutrino Amino Acid Processing Model

TL;DR

This paper explores potential supernova sites capable of producing left-handed amino acids through neutrino interactions, shedding light on the origin of life's chirality asymmetry on Earth.

Contribution

It identifies specific astrophysical sites with suitable magnetic fields and neutrino fluxes that could facilitate amino acid chirality selection in meteoroids.

Findings

Several supernova sites meet the magnetic and neutrino flux criteria.

The model supports supernovae as sources of biological homochirality.

Implications for the origin of life on Earth are discussed.

Abstract

The Supernova Neutrino Amino Acid Processing model, which uses electron anti-neutrinos and the magnetic field from a source object such as a supernova to selectively destroy one amino acid chirality, is studied for possible sites that would produce meteoroids having partially left-handed amino acids. Several sites appear to provide the requisite magnetic field intensities and electron anti-neutrino fluxes. These results have obvious implications for the origin of life on Earth.
