How to see an antistar

Abstract

Polarization of photons emitted in weak decays occuring at distant star allows to determine whether this star is made from antimatter. Even more promissing is the observation of neutrinos (antineutrinos) produced at neutronization (antineutronization) reactions at the beginning of SN ($\overline{SN}$) explosion.

Comment about the experimental measurement of the circular polarization of emitted in nuclear transitions photons added; variant to be published in JETP Letters
