Description
In recent years, the discovery rate of double neutron star
(DNS) systems has
increased rapidly and the coming decade will greatly enhance
the number of both
radio pulsar DNS systems, with the completion of the
Square-Kilometre-Array, and
DNS mergers from detections of high-frequency gravitational
waves using LIGO.
This calls for a new investigation of the formation and
evolution of DNS systems. In
this talk, I will summarise the exotic journey of binary
stars leading to the
production of DNS systems and discuss all their key
parameters. This includes
correlations between spin period (of the first-formed,
mildly recycled NS), orbital
period and eccentricity, based on theoretical modelling. I
discuss NS masses and
the anticipated recorded mass spectrum from near future
LIGO/VIRGO detections
of DNS mergers. Finally, I will discuss NS kicks (magnitude
and direction) with a
surprising result and present a large set of Monte Carlo
simulations of the second
SN in order to extrapolate the pre-SN stellar properties and
probe the explosions of
these ultra-stripped SNe.
