Compact Binary Coalescences: Astrophysical Processes and Lessons Learned

Abstract: On 11 February 2016, the LIGO and Virgo scientific collaborations announced the first direct detection of gravitational waves, a signal caught by the LIGO interferometers on 14 September 2015, and produced by the coalescence of two stellar-mass black holes. The discovery represented the beginning of an entirely new way to investigate the Universe. The latest gravitational-wave catalog by LIGO, Virgo and KAGRA brings the total number of gravitational-wave events to 90, and the count is expected to significantly… Show more

“…We adopt a low metallicity, so that stellar winds are irrelevant (Farmer et al 2019), to avoid the possible numerical complications of resolving models with winds (Renzo et al 2017). Low-metallicity environments are also likely to form some of the most massive stellar-mass BHs that can be detected as GW sources (Mapelli 2021;Vink et al 2021;Mandel & Farmer 2022;Spera et al 2022). Metallicities as low as Z = 0.02 Z e are enough to yield final He core masses of up to 140 M e , when adopting the recently updated and physically motivated Wolf-Rayet mass-loss schemes (Higgins et al 2021).…”

“…In addition, examined the formation of wide-separate triples via dynamical interactions in young star clusters from simulations performed in Rastello et al (2020), and found that the ZKL oscillation plays an important role for the coalescence of compact binaries in such triples. For more comprehensive reviews on the formation of merging compact objects, including the triple evolution channel, we refer the reader to Mapelli (2021) and Spera et al (2022).…”
