Non-conservative Mass Transfer as a Formation Channel for Gaia Black Hole System
Aleksandra Olejak, Jakub Klencki, Alejandro Vigna-Gomez +6
The detected Gaia systems hosting compact objects challenge standard models of binary star evolution. In particular, if the observed black hole (BH) systems evolved in isolation, t…
Resolving Black Hole Family Issues Among the Massive Ancestors of Very High-Spin Gravitational-Wave Events Like GW231123
Jakob Stegmann, Aleksandra Olejak, Selma E. de Mink
The latest detection of GW231123, a binary black hole (BH) merger with exceptionally large masses and high spins for the incoming components, has been suggested as a smoking gun fo…
Thermal-timescale accretion does not always yield critical rotation in mass gainers
Chen Wang, Mike Y. M. Lau, Xiang-Dong Li +7
Binary evolution plays a central role in producing rapidly rotating stars. Previous studies have shown that mass gainers in binaries can reach critical rotation after accreting onl…
Very Massive, Rapidly Spinning Binary Black Hole Progenitors through Chemically Homogeneous Evolution -- The Case of GW231123
Silvia A. Popa, Selma E. de Mink
Among the over 200 gravitational wave detections reported so far, GW231123 is a remarkable event that not only holds the record for the most massive black hole merger, but also exh…
Binary stars take what they get: Evidence for Efficient Mass Transfer from Stripped Stars with Rapidly Rotating Companions
Thibault Lechien, Selma E. de Mink, Ruggero Valli +5
Binary stars and their interactions shape the formation of compact binaries, supernovae, and gravitational wave sources. The efficiency of mass transfer - the fraction of mass reta…
Nuclear Neural Networks: Emulating Late Burning Stages in Core Collapse Supernova Progenitors
Aldana Grichener, Mathieu Renzo, Wolfgang E. Kerzendorf +7
One of the main challenges in modeling massive stars to the onset of core collapse is the computational bottleneck of nucleosynthesis during advanced burning stages. The number of…
