Abstract
When a spinning-down neutron star undergoes a phase transition that produces quark matter in its core, a super-giant glitch of the order ΔΩ/Ω ~ 0.3 occurs on timescales from 0.05 s to a few minutes. The energy released is about 1052 ergs and can account for gamma-ray bursts at cosmological distances. The estimated burst frequency, 10-6 yr-1 per galaxy, is in very good agreement with observations. We also discuss the possibility of distinguishing these events from neutron star mergers by observing the different temporal behavior of gravitational waves.Keywords
