Millisecond radio pulsars in globular clusters

Abstract
Using the standard scenario that all millisecond radio pulsars descend from low-mass X-ray binaries, we show that the number of such pulsars in globular clusters should be larger than ∼ 102, and that most of them are located in a small number of clusters. For example, we predict that Terzan 5 and Liller 1 contain at least ∼ 12 millisecond radio pulsars each. The observations of millisecond radio pulsars in globular clusters to date, in particular the discovery of two millisecond radio pulsars in 47 Tuc, are in complete agreement with the standard scenario. It is unnecessary to postulate that millisecond radio pulsars are formed directly from accretion-induced collapse of white dwarfs.
