This paper uses population synthesis to investigate the possible origin of
isolated millisecond pulsars (IMSPs) as born from the coalescence of a neutron
star (NS) and a white dwarf (WD). Results show that the galactic birth – rate
of IMSPs is likely to lie between $5.8times10^{-5}$ $rm yr^{-1}$ and
$2.0times10^{-4}$ $rm yr^{-1}$, depending on critical variables, such as the
stability of mass transfer via the Roche lobe and the value of kick velocity.
In addition to this, this paper estimates that the solar mass of IMSPs can
range from $1.5$ and 2.0 $M_{odot}$, making them more massive than other
‘normal’ pulsars. Finally, the majority of IMSPs in our simulations have spin
periods ranging from several to 20 milliseconds, which is consistent with
previous observations.
