“…The evolution of the B Ðeld in isolated NSs is still a very controversial issue. Little evidence comes from the pulsar statistics, and one should rely only on theoretical models (see, e.g., Srinivasan 1997). Theoretical results are far from being unequivocal and predict either exponential/ power-law Ðeld decay (Ostriker & Gunn 1969 ;Sang & Chanmugam 1987 ;Urpin, Chanmugam, & Sang 1994 ;Miri 1996 ;Urpin & Muslimov 1992 ;Urpin & Konenkov 1997) or little or no decay at all within the age of the Galaxy (Romani 1990 ;Srinivasan et al 1990 ;Goldreich & Reisenegger 1992 ; see also Lamb 1992 for a review).…”

As many as $10^9$ neutron stars populate the Galaxy, but only $\approx 10^3$ are directly observed as pulsars or as accreting sources in X-ray binaries. In principle also the accretion of the interstellar medium may make isolated neutron stars shine, and their weak luminosity could be detected in soft X-rays. Recent ROSAT observations have convincingly shown that neutron stars accreting from the interstellar medium are extremely rare, if observed at all, in contrast with earlier theoretical predictions. Until now two possible explanations for their elusiveness have been proposed: their velocity distribution may peak at $\sim 200-400 {\rm km s}^{-1}$, as inferred from pulsar statistics, and this would severely choke accretion; the magnetic field may decay on timescales $\sim 10^8-10^9$ yr, preventing a large fraction of neutron stars from entering the accretor stage. The search for accreting neutron stars has produced up to now a handful of promising candidates. While little doubt is left that these objects are indeed isolated neutron stars, the nature of their emission is still controversial. In particular accreting objects can be confused with much younger, cooling neutron stars. However, a combination of observations and theoretical modeling may help in discriminating between the two classes.Comment: 22 pages Latex, 3 Figures, Invited Review to be published to PAS

Neutron stars, the compact stellar remnants of core-collapse supernova explosions, are unique cosmic laboratories for exploring novel phases of matter under extreme conditions. In particular, the occurrence of superfluidity and superconductivity in neutron stars will be briefly reviewed.Comment: Has appeared in Journal of Astrophysics and Astronomy special issue on "Physics of Neutron Stars and Related Objects", celebrating the 75th birth-year of G. Srinivasa
