A Catalog of Potential Post–Common Envelope Binaries

We present a catalogue containing 839 candidate post common envelope systems. Common evolution is very important in stellar astrophysics, particularly the context of compact and short-period binaries, including cataclysmic variables, as progenitors e.g. supernovae type Ia or mergers black holes and/or neutron stars. At same time it barely understood process binary evolution. Due to limitations, since partially remedied, on direct simulation, early investigations were mainly focused providing analytic prescriptions outcome In recent years, detailed hydrodynamical calculations have produced deeper insight into previously elusive ejection. However, link between observations theory this relatively short-lived phase has not been forthcoming. Therefore, main be gained from derived current state systems likely gone through envelope. Here we an extensive such found literature. The aim paper provide reliable set data, obtained observations, used theoretical modelling catalogue, former donor star commonly observed white dwarf hot sub-dwarf star. This includes period mass estimates, wherever obtainable. Some binaries are border line cases allow investigation transition formation other mass-transfer processes.
