Impact of core mass on binary evolution
WitrynaBased on the observed mass distribution, we argue that the $\sim 10\%$ of binary black holes with chirp masses greater than $40$ M$_\odot$ (the maximum predicted by our models) are unlikely to ... 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 …

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 …
