A model for the enhanced production rate of early-type hypervelocity stars in the Galactic halo
Chunyang Cao, F. K. Liu, Xian Chen +1
About twenty late B-type hypervelocity stars (HVSs) traveling faster than the Galactic escape velocity have been discovered in the Galactic halo, many of which were ejected from th…
The Faintest, Extremely Variable X-ray Tidal Disruption Event from a Supermassive Black Hole Binary?
Mengqiu Huang, Yongquan Xue, Shuo Li +30
Tidal disruption events (TDEs), which occur when stars enter the tidal radii of supermassive black holes (SMBHs) and are subsequently torn apart by their tidal forces, represent in…
Formation Rate of Quasiperiodic Eruptions in Galactic Nuclei Containing Single and Dual Supermassive Black Holes
Chunyang Cao, F. K. Liu, Xian Chen +1
Quasiperiodic eruptions (QPEs) are a novel class of transients recently discovered in a few extragalactic nuclei. It has been suggested that a QPE can be produced by a main-sequenc…
A Recent Supermassive Black Hole Binary in the Galactic Center Unveiled by the Hypervelocity Stars
Chunyang Cao, Fukun Liu, Shuo Li +2
When a binary of early-type stars from the young stellar populations in the Galactic center (GC) region is scattered to the vicinity of the supermassive black hole (SMBH) Sgr~$\rm{…
S-type stars from LAMOST DR10: classification of intrinsic and extrinsic stars
Jing Chen, Yin-Bi Li, A-Li Luo +2
In this paper, we found 2939 S-type stars from LAMOST Data Release 10 using two machine-learning methods, and 2306 of them were reported for the first time. The main purpose of thi…
Tracing the Evolution of SMBHs and Stellar Objects in Galaxy Mergers: An Multi-mass Direct N-body Model
Shuo Li, Shiyan Zhong, Peter Berczik +3
By using direct N-body numerical simulations, we model the dynamical co-evolution of two supermassive black holes (SMBHs) and the surrounding stars in merging galaxies. In order to…
Identification and parameter determination of F-type Herbig stars from LAMOST DR8
Yun-Jin Zhang, A-Li Luo, Bi-Wei Jiang +5
We identify 20 F-type Herbig stars and provide a list of 22 pre-main-sequence candidates from LAMOST DR8. The effective temperature, distance, extinction, stellar luminosity, mass,…
Revisit the rate of tidal disruption events: the role of the partial tidal disruption event
Shiyan Zhong, Shuo Li, Peter Berczik +1
Tidal disruption of stars in dense nuclear star clusters containing supermassive central black holes (SMBH) is modeled by high-accuracy direct N-body simulation. Stars getting too…
Milli-Hertz Gravitational Wave Background Produced by Quasi-Periodic Eruptions
Xian Chen, Yu Qiu, Shuo Li +1
Extreme-mass-ratio inspirals (EMRIs) are important targets for future space-borne gravitational-wave (GW) detectors, such as the Laser Interferometer Sapce Antenna (LISA). Recent w…
A catalog of early-type Hα emission line stars and 58 newly confirmed Herbig Ae/Bes from LAMOST DR7
Yun-Jun Zhang, Wen Hou, A-Li Luo +6
We derive a catalog of early-type emission-line stars including 30,048 spectra of 25,886 stars from LAMOST DR7, in which 3,922 have Simbad records. The sample is obtained using K-N…
X-ray flares from the stellar tidal disruption by a candidate supermassive black hole binary
Xinwen Shu, Wenjie Zhang, Shuo Li +8
Optical transient surveys have led to the discovery of dozens of stellar tidal disruption events (TDEs) by massive black hole in the centers of galaxies. Despite extensive searches…
Exploring the origin of stars on bound and unbound orbits causing tidal disruption events
Shiyan Zhong, Kimitake Hayasaki, Shuo Li +2
Tidal disruption events (TDEs) provide a clue to the properties of a central supermassive black hole (SMBH) and an accretion disk around it, and to the stellar density and velocity…
Measuring black hole masses from tidal disruption events and testing the relation
Z. Q. Zhou, F. K. Liu, S. Komossa +4
Liu and collaborators recently proposed an elliptical accretion disk model for tidal disruption events (TDEs). They showed that the accretion disks of optical/UV TDEs are large and…
Direct n-body simulations of tidal disruption rate evolution in unequal-mass galaxy mergers
Shuo Li, Peter Berczik, Xian Chen +3
The hierarchical galaxy formation model predicts supermassive black hole binaries (SMBHBs) in galactic nuclei. Due to the gas poor environment and the limited spatial resolution in…
Classification of Tidal Disruption Events Based on Stellar Orbital Properties
Kimitake Hayasaki, Shiyan Zhong, Shuo Li +2
We study the rates of tidal disruption of stars by intermediate-mass to supermassive black holes on bound to unbound orbits by using high-accuracy direct N-body experiments. The ap…
Mass-redshift Degeneracy for Gravitational-wave Sources in the Vicinity of a Supermassive Black Hole
Xian Chen, Shuo Li, Zhoujian Cao
Retrieving the mass of a gravitational-wave (GW) source is a fundamental but difficult problem because the mass is degenerate with redshift. In astronomy, three types of redshift e…
