Astrophysical Implications of Eccentricity in Gravitational Waves from Neutron Star-Black Hole Binaries
Isobel Romero-Shaw, Jakob Stegmann, Gonzalo Morras +2
The gravitational-wave signal from the neutron star-black hole (NSBH) merger GW200105 is consistent with this binary having significant orbital eccentricity close to merger. This r…
Hierarchical Triples vs. Globular Clusters: Binary black hole merger eccentricity distributions compete and evolve with redshift
Andris Dorozsmai, Isobel M. Romero-Shaw, Aditya Vijaykumar +5
The formation mechanisms of merging binary black holes (BBHs) observed by the LIGO-Virgo-KAGRA collaboration remain uncertain. Detectable eccentricity provides a powerful diagnosti…
Diversity in Hydrogen-rich Envelope Mass of Type II Supernovae. (III). The mass-loss and evolutionary pathways of the red supergiant progenitors
Qiliang Fang, Takashi J. Moriya, Keiichi Maeda +2
We present a comprehensive analysis of 32 type II supernovae (SNe II) with plateau phase photometry and late phase () spectroscopy available, aiming to bridge the gap betw…
Prompt stellar and binary black hole mergers in tight triples: Insights from chemically homogeneous evolution
Alejandro Vigna-Gómez, Evgeni Grishin, Jakob Stegmann +7
Short-period massive binary stars are predicted to undergo chemically homogeneous evolution (CHE), making them prime candidates for producing binary black holes (BBHs) that may mer…
