Astrophysical limits on the flux of quark nuggets
Abstract
Limits on the galactic flux of quark nuggets are improved by many orders of magnitude on the assumption that pulsars exhibiting glitches must be neutron stars, not strange stars. Therefore no quark nuggets can have settled in the core of the neutron star progenitor or have penetrated to the neutron-drip region after the pulsar was formed. This excludes nuggets with baryon number A<1035 as possible dark-matter candidates. The existence of strange stars in binary systems is questions, and it is argued that quark nuggets are unlikely explanations of the solar neutrino problem.
