假设出现故障的脉冲星一定是中子星，而不是奇怪的恒星，那么夸克块的星系通量的限制就提高了许多个数量级。因此，在脉冲星形成后，没有夸克块能够沉淀在中子星祖先的核心或渗透到中子滴区。这排除了重子数A< 10 35的块状物质作为可能的暗物质候选者。双星系统中奇异恒星的存在受到质疑，而且有人认为夸克块不太可能解释太阳中微子问题。
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< 10 35 as possible dark-matter candidates. The existence of strange stars in binary systems is questioned, and it is argued that quark nuggets are unlikely explanations of the solar neutrino problem.
