WitrynaEclipsing post-common-envelope binaries are highly important for resolving the poorly understood, very short-lived common-envelope phase of stellar evolution. Most hot subdwarfs (sdO/Bs) are the bare helium-burning cores of red giants that have lost almost all of their hydrogen envelope. This mass loss is often triggered by common-envelope … Witryna22 gru 2024 · We demonstrate how the definition of the core-envelope boundary, the nature of the energy sources, metallicity, stellar mass, and evolutionary stage influence the value of λ parameters. ... it will be self-consistent to test our new CE prescriptions and study their impact on the evolutionary pathways of binary systems.

WitrynaGenerally, we find that the low-mass binary (BWD) mergers do not show pronounced difference in the ISO and in the N-body models. When massive BBHs exist, they dominate the binary heating process by which the dynamical impact on the low-mass binaries is strongly suppressed, as shown in Fig. 4. We expect that the dynamical … Witryna1981), accretors are expected to adjust their core-size to the new mass in a \rejuvenation" process (e.g.,Neo et al. 1977;Hellings1983,1984).
