✦ Synopsis


A solitary millisecond pulsar, if near the mass limit, and undergoing a phase transition, either first or second order, provided the transition is to a substantially more compressible phase, will emit a blatantly obvious signal-spontaneous spin-up. Normally a pulsar spins down by angular momentmn loss to radiation. The signal is trivial to detect and is estimated to be "on" for 1/50 of the spin-down era of nfillisecond pulsars. Presently about 25 solitary millisecond pulsars are known. The phenomenon is analogous to "backbending" observed in high spin nuclei in the 1970's.

Using percolation theory, we derive a conceptual definition of deconfinement in terms of cluster formation. The result is readily applicable to infinite volume equilibrium matter as well as to finite size pre-equilibrium systems in nuclear collisions.
