Fast radio bursts from strange quark stars 
Huang, Yongfeng
Strange quark stars are compact objects made of deconfined quarks. We argued that when the crust of a strange star collapses, a fast radio burst could be produced. We further suggest that repeating fast radio bursts can be produced by the intermittent fractional collapses of the crust of a strange quark star induced by refilling of materials accreted from its low-mass companion. The periodic behaviors of the repeating FRB 180916 could be well understood in our scenario.
