Low Mass X-ray Binary As the Progenitor of PSR J1713+0747
We have calculated the evolution of low-mass X-ray binaries that leads to the
formation of the binary radio pulsars like PSR J1713+0747. We show that the
mass transfer is most likely to be nonconservative, due to unstable disk
accretion, to account for the mass of PSR J1713+0747, which is close to its
initial value. We assume that part of the lost material from the binary may
form a circumbinary disk, and find that it can significantly influence the mass
transfer processes. We briefly discuss the implications of the circumbinary
disks on the evolution of low-mass X-ray binaries and the formation of low-mass
binary pulsars.Comment: 8 pages, 4 figures, accepted for publication in PAS
