Close double neutron stars have been observed as Galactic radio pulsars,while their mergers have been detected as gamma-ray bursts andgravitational-wave sources. They are believed to have experienced at least onecommon-envelope episode during their evolution prior to double neutron starformation. In the last decades there have been numerous efforts to understandthe details of the common-envelope phase, but its computational modellingremains challenging. We present and discuss the properties of the donor and thebinary at the onset of the Roche-lobe overflow leading to these common-envelopeepisodes as predicted by rapid binary population synthesis models. Theseproperties can be used as initial conditions for detailed simulations of thecommon-envelope phase. There are three distinctive populations, classified bythe evolutionary stage of the donor at the moment of the onset of theRoche-lobe overflow: giant donors with fully-convective envelopes, cool donorswith partially-convective envelopes, and hot donors with radiative envelopes.We also estimate that, for standard assumptions, tides would not circularise alarge fraction of these systems by the onset of Roche-lobe overflow. This makesthe study and understanding of eccentric mass-transferring systems relevant fordouble neutron star populations.
