Binary and Millisecond Pulsars
We review the main properties, demographics and applications of binary and millisecond radio pulsars. Our knowledge of these exciting objects has greatly increased in recent years, mainly due to successful surveys which have brought the known pulsar population to over 1700. There are now 80 binary and millisecond pulsars associated with the disk of our Galaxy, and a further 103 pulsars in 24 of...
متن کاملBinary and Millisecond Pulsars
Most of the ~600 known pulsars are single and located in the disk of our Galaxy. There is circumstantial evidence that the pulsars in this majority are created in supernova (SN) explosions, by the collapse of the cores of massive stars (initial mass Mi >~ Met "~ 8 Mo). One is created roughly every 100 y in the Galaxy. Figure 1 is a plot of the pulse period (P) versus the dipole field strength (...
متن کاملEccentric Binary Millisecond Pulsars
In this paper we review recent discovery of millisecond pulsars (MSPs) in eccentric binary systems. Timing these MSPs we were able to estimate (and in one case precisely measure) their masses. These results suggest that, as a class, MSPs have a much wider range of masses (1.3 to > 2M⊙) than the normal and mildly recycled pulsars found in double neutron star (DNS) systems (1.25 < Mp < 1.44M⊙). T...
متن کاملThe orbital period distribution of wide binary millisecond pulsars
We present results of a binary population synthesis study on the orbital period distribution of wide binary millisecond pulsars forming through four evolutionary channels. In three of the channels, the progenitor of the millisecond pulsar undergoes a common envelope phase prior to the supernova explosion which gives birth to the neutron star. In the fourth channel, the primary avoids the common...
متن کاملDiscovery of Short-period Binary Millisecond Pulsars in Four Globular Clusters
We report the discovery using the Parkes radio telescope of binary millisecond pulsars in four clusters for which no associated pulsars were previously known. The four pulsars have pulse periods lying between 3 and 6 ms. All are in circular orbits with low-mass companions and have orbital periods of a few days or less. One is in a 1.7-hour orbit with a companion of planetary mass. Another is ec...
