Formation of millisecond pulsars
We have performed detailed numerical calculations of the non-conservative evolution of close binary systems with low-mass (1.0 − 2.0M⊙) donor stars and a 1.3M⊙ accreting neutron star. Rather than using analytical expressions for simple polytropes, we calculated the thermal response of the donor star to mass loss, in order to determine the stability and follow the evolution of the mass transfer....
متن کاملBinary 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 کاملAccretion-powered millisecond pulsars
I review X-ray observations of accretion-powered millisecond pulsars and current theories for formation of their spectra and pulse profiles.
