“…In Gallegos-Garcia et al (2021) we simulated MT at 10 ṀEdd for grids of BH-H-rich star binaries with a maximum MS donor mass of 40M . We found that the BH mass can increase by at least a factor of 1.3, similar to that shown in Shao & Li (2022), but only for initial orbital periods 2.5 days when the system is a BH-H-rich star binary. The contribution of BBHs from this scenario may therefore be similar to the mechanisms mentioned above that invoke accretion rates above the Eddington limit.…”

“…In a recent study, Shao & Li (2022) showed that a slow phase of stable Case-A MT lasting ∼ 0.7 Myr from an 80M MS donor onto a 30M BH with an initial orbital period of 4 days can form a BBH with a component spin of ∼ 0.6. This is unlike the Case-A MT studied here, which occurs between two MS stars.…”

Gravitational-wave observations of binary black hole (BBH) systems point to black hole spin magnitudes being relatively low. These measurements appear in tension with high spin measurements for high-mass X-ray binaries (HMXBs). We use grids of MESA simulations combined with the rapid population-synthesis code COSMIC to examine the origin of these two binary populations. It has been suggested that Case-A mass transfer while both stars are on the main sequence can form high-spin BHs in HMXBs. Assuming this formation channel, we show that depending on critical mass ratios for the stability of mass transfer, 48-100% of these Case-A HMXBs merge during the common-envelope phase and up to 42% result in binaries too wide to merge within a Hubble time. Both MESA and COSMIC show that high-spin HMXBs formed through Case-A mass transfer can only form merging BBHs within a small parameter space where mass transfer can lead to enough orbital shrinkage to merge within a Hubble time. We find that only up to 11% of these Case-A HMXBs result in BBH mergers, and at most 20% of BBH mergers came from Case-A HMXBs. Therefore, it is not surprising that these two spin distributions are observed to be different.

“…It certainly remains possible that the binary black hole mergers witnessed by Advanced LIGO and Virgo contain sub-populations of non-spinning and/or nearlyaligned binaries, but this scenario is not presently required by gravitational-wave observations. If such subpopulations were to appear in an analysis of future data, they could be taken as evidence towards the hypothesis that merging black holes are born in the stellar field, with spins acquired primarily through tidal spin-up (Galaudage et al 2021;Olejak & Belczynski 2021;Belczynski et al 2021;Stevenson 2022;Mandel & Farmer 2022;Shao & Li 2022). Such astrophysical conclusions are currently unsupported by the data, however.…”

The spin properties of merging black holes observed with gravitational waves can offer novel information about the origin of these systems. The magnitude and orientations of black hole spins offer a record of binaries' evolutionary history, encoding information about massive stellar evolution and the astrophysical environments in which binary black holes are assembled. Recent analyses of the binary black hole population have yielded conflicting portraits of the black hole spin distribution. Some work suggests that black hole spins are small but non-zero and exhibit a wide range of misalignment angles relative to binaries' orbital angular momenta. Other work concludes that the majority of black holes are non-spinning while the remainder are rapidly rotating and primarily aligned with their orbits. We revisit these conflicting conclusions, employing a variety of complementary methods to measure the distribution of spin magnitudes and orientations among binary black hole mergers. We find that the existence of a sub-population of black hole with vanishing spins is not required by current data. Should such a sub-population exist, we find that it must contain 60% of binaries. Additionally, we find evidence for significant spin-orbit misalignment among the binary black hole population, with some systems exhibiting misalignment angles greater than 90 • , and see no evidence for an approximately spin-aligned sub-population.
