Interactions with a companion star may change the final rate of rotation, … Witrynadetected. If these BBHs are the product of binary evolution, then PPISNe could occur in very close binaries. Motivated by this, we discuss the implications of a PPISN happening with a close binary companion and what impact these events have on the formation of merging BBHs through binary evolution.

To apply the results easily to binary population synthesis, we fit two formulae for the remnant mass as a … Witryna6 mar 2024 · Thorne–Żytkow objects (TŻOs), originally proposed by Thorne and Żytkow, may form as a result of unstable mass transfer in a massive X-ray binary after a neutron star (NS) is engulfed in the envelope of its companion star. Using a rapid binary evolution program and the Monte Carlo method, we simulated the formation of TŻOs … pumpkin fest silver dollar city

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 … Witryna1 cze 2024 · The growing sample of LIGO–Virgo black holes (BHs) opens new perspectives for the study of massive binary evolution.
