Description

Hybrid stars, also know as Thorne-Zytkow Objects (TZOs), have been predicted to form when a neutron star is engulfed by by another star, likely a red giant or super-giant. Then, accretion onto a neutron star can lead to a significant emission of neutrinos of all flavours with energies of 1–100 MeV. Since the neutrino signal is expected to largely vary in time (from milliseconds to thousands of years), we propose detection strategies tailored to the signal duration. We find that neutrino detection from TZOs up to the Small Magellanic Cloud is within the reach of current- and next-generation neutrino telescopes. Neutrino searches complement the ongoing observational efforts across the electromagnetic spectrum and gravitational wave detection prospects and would be of pivotal importance to probe this population of exotic stellar objects.
