Formation of black hole stars via star--black hole collisions
Yanlong Shi, Qingru Hu, Zhenghao Xu +2
In dense stellar environments such as globular clusters and active galactic nucleus (AGN) disks, stellar-mass black holes (sBHs) may frequently collide with massive stars. We inves…
Dynamical formation of high-eccentricity compact binaries through BH--BH*/TZO collisions
Qingru Hu, Yanlong Shi, Douglas N. C. Lin +1
The rapidly accumulating discoveries of binary stellar-mass black-hole (sBH) coalescences, detected by LIGO, have opened a new window into the formation and evolution of compact bi…
Stellar mergers and chemical element mixing: implications for the metamorphic stellar evolution in AGN disks
Yanlong Shi, Xiaoshan Huang, Douglas N. C. Lin +1
Chemical mixing during stellar mergers can significantly influence the subsequent evolution of the merger remnant. We perform a suite of three-dimensional hydrodynamical simulation…
Very Massive Stars and High N/O: A Tale of the Nitrogen-enriched Super Star Cluster in the Sunburst Arc
Yanlong Shi, Liang Dai, Norman Murray +3
The lensed Sunburst Arc () hosts a young (--), massive (), compact () Lyman-continuum (LyC) le…
Zooming In On The Multi-Phase Structure of Magnetically-Dominated Quasar Disks: Radiation From Torus to ISCO Across Accretion Rates
Philip F. Hopkins, Kung-Yi Su, Norman Murray +12
Recent radiation-thermochemical-magnetohydrodynamic simulations resolved formation of quasar accretion disks from cosmological scales down to ~300 gravitational radii , argu…
