PULSAR SIGNAL OF DECONFINEMENT

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