Can isolated binaries form unequal-mass binary black-hole mergers with a high-spin primary black hole?
Xiao-Tian Xu, Dong Lai, Bin Liu
GWTC-5 has revealed a subpopulation of merging binary black holes (BBHs) with a high-spin primary black hole (BH) and possibly unequal BH masses. GW241110 additionally exhibits a l…
Interacting binaries on the Main Sequence as in-situ tracers of mass transfer efficiency and stability
Koushik Sen, Mathieu Renzo, Harim Jin +8
Understanding the transfer of mass and angular momentum in binary interactions is crucial for modelling the evolution of any interacting binary after the first mass transfer phase.…
Subgiants in NGC 188 Reveal that Rotationally Induced Mixing Creates the Main Sequence Li-Dip
Qinghui Sun, Constantine P. Deliyannis, Barbara J. Anthony-Twarog +3
The "Li-Dip" is an unexpected, striking, and highly non-standard anomaly of severe lithium depletion observed in mid-F dwarf stars, which has puzzled astronomers for nearly 40 year…
Using detailed single star and binary evolution models to probe the large observed luminosity spread of red supergiants in young open star clusters
Chen Wang, Lee Patrick, Abel Schootemeijer +12
Red supergiants (RSGs) represent a late evolutionary stage of massive stars. Recent observations reveal that the observed luminosity range of RSGs in young open clusters is wider t…
Stripped helium-star and compact object binaries in coeval populations -- predictions based on detailed binary evolution models
Chen Wang, Julia Bodensteiner, Xiao-Tian Xu +9
Massive stars mainly form in close binaries, where their mutual interactions can profoundly alter their evolutionary paths. Evolved binaries consisting of a massive OB-type main-se…
Unequal-mass, highly-spinning binary black hole mergers in the stable mass transfer formation channel
Aleksandra Olejak, Jakub Klencki, Xiao-Tian Xu +3
The growing database of gravitational-wave (GW) detections with the binary black holes (BHs) merging in the distant Universe contains subtle insights into their formation scenarios…
Back to the Starting Point: on the Simulation of Initial Magnetic Fields and Spin Periods of Non-accretion Pulsars
Kun Xu, Hao-Ran Yang, Ying-Han Mao +3
Neutron stars (NSs) play essential roles in modern astrophysics. Magnetic fields and spin periods of newborn (zero age) NSs have large impact on the further evolution of NSs, which…
Stellar mergers as the origin of the blue main-sequence band in young star clusters
Chen Wang, Norbert Langer, Abel Schootemeijer +10
Recent high-quality Hubble Space Telescope (HST) photometry shows that the main sequences (MS) stars of young star clusters form two discrete components in the color-magnitude diag…
Explodability fluctuations of massive stellar cores enable asymmetric compact object mergers such as GW190814
John Antoniadis, David R. Aguilera-Dena, Alejandro Vigna-Gómez +6
The first three observing runs with Advanced LIGO and Virgo have resulted in the detection of binary black hole mergers (BBH) with highly unequal mass components, which are difficu…
X-ray emission from BH+O star binaries expected to descend from the observed galactic WR+O binaries
K. Sen, X. -T. Xu, N. Langer +3
In the Milky Way, 18 Wolf-Rayet+O (WR+O) binaries are known with estimates of their stellar and orbital parameters. Whereas black hole+O (BH+O) binaries are thought to evolve…
Properties of OB star-black hole systems derived from detailed binary evolution models
N. Langer, C. Schürmann, K. Stoll +38
The recent gravitational wave measurements have demonstrated the existence of stellar mass black hole binaries. It is essential for our understanding of massive star evolution to i…
