Probing strange quark matter objects with future space-based gravitational wave detectors DECIGO and BBO
Abdusattar Kurban, Xia Zhou, Na Wang +9
The Strange Quark Matter (SQM) hypothesis posits that objects composed of SQM could exist across a wide mass range, from strange planets (SPs) to strange stars (SSs). It has been p…
Multi-messenger View of White Dwarf Tidal Disruption Events by Intermediate-Mass Black Holes: I. Gravitational Waves and Disk Photon and Neutrino Emissions
Jin-Hong Chen, Lixin Dai, Bing Zhang
White dwarf (WD) tidal disruption events (TDEs) provide a unique window onto intermediate-mass black holes (IMBHs). We present a multi-messenger view of these systems in two papers…
X-ray variability of SDSS J000532.84+200717.4: from a normal state to an X-weak state
Xiaohui Yang, Yanli Ai, Liming Dou +8
We present a multi-epoch study of the extreme X-ray variability of the type~1 quasar SDSS~J000532.84+200717.4 using archival observations from \textit{XMM-Newton}, \textit{Swift}/X…
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…
Simulating the late stages of WD-BH/NS mergers: an origin for fast X-ray transients and GRBs with periodic modulations
Jun-Ping Chen, Rong-Feng Shen, Jin-Hong Chen +1
Recent studies indicate that mergers of a white dwarf (WD) with a neutron star (NS) or a stellar-mass black hole (BH) may be a potential progenitor channel for certain merger-kind,…
A fast powerful X-ray transient from possible tidal disruption of a white dwarf
Dongyue Li, Wenda Zhang, Jun Yang +97
Stars captured by black holes (BHs) can be torn apart by strong tidal forces, producing electromagnetic flares. To date, more than 100 tidal disruption events (TDEs) have been obse…
EP241021a: a months-duration X-ray transient with luminous optical and radio emission
Shu Xinwen, Yang Lei, Yang Haonan +82
We present the discovery of a peculiar X-ray transient, EP241021a, by the Einstein Probe (EP) mission, and the results from multiwavelength follow-up observations. The transient wa…
Fate of the remnant in tidal stripping event: repeating and non-repeating
Jin-Hong Chen, Lixin Dai, Shang-Fei Liu +1
Tidal disruption events (TDE) occur when a star ventures too close to a massive black hole. In a partial TDE (pTDE), the star only grazes the tidal radius, causing the outer envelo…
GWnext 2024: Meeting Summary
Alejandro Torres-Orjuela, Veronica Vazquez-Aceves, Rui Xu +19
GWnext 2024 was a meeting held in the Kavli Institute for Astronomy and Astrophysics at Peking University in March , 2024. In the meeting researchers at…
Tidal Stripping of a White Dwarf by an Intermediate-Mass Black Hole
Jin-Hong Chen, Rong-Feng Shen, Shang-Fei Liu
During the inspiralling of a white dwarf (WD) into an intermediate-mass black hole (~ 10^{2-5} M_sun), both gravitational waves (GWs) and electromagnetic (EM) radiation are emitted…
AT2019 avd: A tidal disruption event with a two-phase evolution
Jin-Hong Chen, Li-Ming Dou, Rong-Feng Shen
Tidal disruption events (TDEs) can uncover the quiescent supermassive black holes (SMBHs) at the center of galaxies. After the disruption of a star by a SMBH, the highly elliptical…
Light Curves of Partial Tidal Disruption Events
Jin-Hong Chen, Rong-Feng Shen
Tidal disruption events (TDEs) can uncover the quiescent black holes (BHs) at the center of galaxies and also offer a promising method to study them. In a partial TDE (PTDE), the B…
