Unveiling the nature of G6096: a likely hierarchical triple system
Yinghao Xu, Xinlin Zhao, Song Wang +10
The authors re‑examine the object G6096, previously thought to be a wide binary with a compact companion, and using spectroscopy, radial‑velocity and astrometric analysis together…
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…
