Description
We present a general picture for the evolution of
relativistic binary systems, including those
recycling NSs to millisecond periods, and those ending in
“redbacks” and “black widow” systems . The
theoretical framework includes all physical effects though
to be relevant for the description of mass transfer $\dot{M}$
namely accretion, evaporation of matter by pulsar irradiation
and X-rays irradiation feedback. We follow evolutionary tracks
and show that the interplay of $\dot{M}$
and orbital evolution, calculated with a fully
implicit code, is capable of explaining the whole variety of
observed binary systems.
In particular, we show that “redback” systems are just a
transitory (but very long) stage driven by an
oscillatory mass transfer. Finally,
we demonstrate that very high masses $\geq 2 M_{\odot}$
are a natural outcome and match the observed values
reported recently for the NS in these systems.
