Unveiling the nature of G6096: a likely hierarchical triple system
Yinghao Xu, Xinlin Zhao, Song Wang +10
G6096 (Gaia DR3 609651611028044544) was recently reported as a wide ( days) and eccentric () binary possibly hosting a massive white dwarf or neutron star. In…
Characterizing Orbital Parameters of Hot Subdwarf Binaries with Multiple Spectroscopic Surveys
XInlin Zhao, Song Wang, Zhenxin Lei +5
Hot subdwarfs (HSDs) provide critical insights into the physical mechanisms governing binary evolution. In this work, we conduct a systematic analysis of 157 HSDs, selected from Ga…
Nature of HD 251108: an RS CVn binary with a long-term evolving spot
Xinlin Zhao, Song Wang, B. Fuhrmeister +5
Recently, the Lobster Eye Imager for Astronomy (LEIA) detected the longest-lasting and most energetic stellar X-ray flare event from HD 251108. In this work, we re-determined the a…
Hydrodynamical simulation of wind production from hot accretion flows in tidal disruption events
Mingjun Liu, De-Fu Bu, Xiao-Hong Yang +5
Wind is a key mechanism for supermassive black hole (SMBH) feedback to their host galaxies. In tidal disruption events (TDEs), black holes spend most of their time accreting at hig…
Radiative cooling effects on black hole hot accretion flows around the sub-Bondi radius
Mu-Qing Liu, Xiao-Hong Yang, De-Fu Bu
It is difficult to implement numerical simulations on a region extending from the vicinity of a black hole to the Bondi radius. Most previous numerical simulations have primarily c…
Numerical Simulations of the Circularized Accretion Flow in Population III Star Tidal Disruption Events. II. Radiative Properties
Yu-Heng Sheng, De-Fu Bu, Liang Chen +3
Tidal Disruption Events (TDEs) release enormous amounts of energy, offering a promising avenue for detecting Population III (Pop III) stars. However, the radiative properties of TD…
Numerical simulations of cold clumps in the hot accretion flows around black holes
Na-Duo Liu, Yu-Heng Sheng, De-Fu Bu +3
Previous numerical simulations have shown that cold clumps can form within hot accretion flows, offering insights into the detailed processes of the state transition in black hole…
