Abstract: |
Common envelope is the most important evolutionary process in the
formation of all close compact binaries. It is well known that during
the common envelope phase a fraction of the orbital energy is used to
expel the envelope. However, it is not clear yet whether or not
additional energy sources, such as the recombination energy of the
envelope, play a decisive role. Here we demonstrate that
recombination energy can only be considered as important if close
binaries containing high-mass white dwarfs (Mwd ≥ 0.8M☉) at
relatively long orbital periods (Porb ≥ 1–3 days) exist. |
