We report on the discovery of PSR J1141[6545, a radio pulsar in an eccentric, relativistic 5 hr binary orbit. The pulsar shows no evidence of being recycled, having a pulse period P \ 394 ms, a characteristic age yr, and an inferred surface magnetic dipole Ðeld strength B \ 1.3 ] 1012 G. From the q c \ 1.4 ] 106 mass function and measured rate of periastron advance, we determine the total mass in the system to be 2.300^0.012 assuming that the periastron advance is purely relativistic. Under the same assump-M _ , tion we constrain the pulsarÏs mass to be and the companionÏs mass to be968 (both with 99% conÐdence). Given the total system mass and the distribution of measured neutron M _ star masses, the companion is probably a massive white dwarf that formed prior to the birth of the pulsar. Optical observations can test this hypothesis.

“…This is an order of magnitude below than the value found by Blinnikov et al (1990) in the more idealised approximation of the fully catalyzed matter. The numerical approach of Colpi et al (1993) is more accurate than ours; still, improvements in their scheme are still possible. There also remain some interesting questions regarding physical processes: the evolution of a hot newborn neutron star may follow another path than that of an old time, ms k 7|£ gr |-cold one, as investigated in the cited papers; the descripton of neutrino transfer may be important, etc.…”

“…Finally, the problem of the explosion of a neutron star below the minimum stable mass deserves special attention. Recently, Colpi, Shapiro & Teukolsky (1993) have found that the energy release by /3-decays leads to an explosion with E k ~ 0.5 x 10 50 ergs. This is an order of magnitude below than the value found by Blinnikov et al (1990) in the more idealised approximation of the fully catalyzed matter.…”

“…Well known examples are white dwarfs and neutron stars, where electrons and neutrons support the degeneracy pressure, respectively. In each case, stability analysis predicts an allowed mass window; for instance, white dwarfs with masses beyond ∼ 1.5 M (the Chandrasekhar limit) collapse into neutron stars, and neutron stars with masses below ∼ 0.2 M and beyond ∼ 3 M are unstable [81,82]. Also, any compact star with mass larger than ∼ 20 M would collapse into a black hole.…”

Non-collider searches for stable massive particles

The theoretical motivation for exotic stable massive particles (SMPs) and the results of SMP searches at non-collider facilities are reviewed. SMPs are defined such that they would be sufficiently long-lived so as to still exist in the cosmos either as Big Bang relics or secondary collision products, and sufficiently massive such that they are typically beyond the reach of any conceivable accelerator-based experiment. The discovery of SMPs would address a number of important questions in modern physics, such as the origin and composition of dark matter and the unification of the fundamental forces. This review outlines the scenarios predicting SMPs and the techniques used at non-collider experiments to look for SMPs in cosmic rays and bound in matter. The limits so far obtained on the fluxes and matter densities of SMPs which possess various detection-relevant properties such as electric and magnetic charge are given.
