Tidal disruption rate suppression by the event horizon of spinning black holes
Hao-Tse Huang, Wenbin Lu
The rate of observable tidal disruption events (TDEs) by the most massive black holes (BHs) is suppressed due to direct capture of stars by the event horizon. This suppression effe…
A very luminous jet from the disruption of a star by a massive black hole
Igor Andreoni, Michael W. Coughlin, Daniel A. Perley +78
Tidal disruption events (TDEs) are bursts of electromagnetic energy released when supermassive black holes (SMBHs) at the centers of galaxies violently disrupt a star that passes t…
Hard X-ray Observations of the Hydrogen-poor Superluminous Supernova SN 2018hti with NuSTAR
Igor Andreoni, Wenbin Lu, Brian Grefenstette +3
Some Hydrogen-poor superluminous supernovae are likely powered by a magnetar central engine, making their luminosity larger than common supernovae. Although a significant amount of…
Optical measurement of superluminal motion in the neutron-star merger GW170817
Kunal P. Mooley, Jay Anderson, Wenbin Lu
The afterglow of the binary neutron star merger GW170817 gave evidence for a structured relativistic jet and a link between such mergers and short gamma-ray bursts. Superluminal mo…
Quasi-periodic eruptions from mildly eccentric unstable mass transfer in galactic nuclei
Wenbin Lu, Eliot Quataert
We propose that the recently observed quasi-periodic eruptions (QPEs) in galactic nuclei are produced by unstable mass transfer due to Roche lobe overflow of a low-mass main-sequen…
Prospects for Detecting Fast Radio Bursts in Globular Clusters of Nearby Galaxies
Kyle Kremer, Dongzi Li, Wenbin Lu +2
The recent detection of a repeating fast radio burst (FRB) in an old globular cluster in M81 challenges traditional FRB formation mechanisms based on magnetic activity in young neu…
A luminous fast radio burst that probes the Universe at redshift 1
Stuart D. Ryder, Keith W. Bannister, S. Bhandari +18
Fast radio bursts (FRBs) are millisecond-duration pulses of radio emission originating from extragalactic distances. Radio dispersion on each burst is imparted by intervening plasm…
Propagation of Alfvén waves in the charge starvation regime
Pawan Kumar, Ramandeep Gill, Wenbin Lu
We present numerical simulation results for the propagation of Alfvén waves in the charge starvation regime. This is the regime where the plasma density is below the critical value…
Late-time accretion in neutron star mergers: implications for short gamma-ray bursts and kilonovae
Wenbin Lu, Eliot Quataert
We study the long-term (t >> 10 s) evolution of the accretion disk after a neutron star(NS)-NS or NS-black hole merger, taking into account the radioactive heating by r-process nuc…
Spectropolarimetry of the tidal disruption event AT 2019qiz: a quasispherical reprocessing layer
Kishore C. Patra, Wenbin Lu, Thomas G. Brink +3
We present optical spectropolarimetry of the tidal disruption event (TDE) AT 2019qiz on days and relative to maximum brightness. Continuum polarization, which informs th…
The Tidal Disruption Event AT2021ehb: Evidence of Relativistic Disk Reflection, and Rapid Evolution of the Disk-Corona System
Yuhan Yao, Wenbin Lu, Muryel Guolo +29
We present X-ray, UV, optical, and radio observations of the nearby ( Mpc) tidal disruption event (TDE) AT2021ehb/ZTF21aanxhjv during its first 430 days of evolution. AT…
On rapid binary mass transfer -- I. Physical model
Wenbin Lu, Jim Fuller, Eliot Quataert +1
In some semi-detached binary systems, the donor star may transfer mass to the companion at a very high rate. We propose that, at sufficiently high mass-transfer rates such that the…
Temporal Scattering, Depolarization, and Persistent Radio Emission from Magnetized Inhomogeneous Environments Near Repeating Fast Radio Burst Sources
Yuan-Pei Yang, Wenbin Lu, Yi Feng +2
Some repeating fast radio burst (FRB) sources exhibit complex polarization behaviors, including frequency-dependent depolarization, variation of rotation measure (RM), and oscillat…
Frequency-dependent polarization of repeating fast radio bursts-implications for their origin
Yi Feng, Di Li, Yuan-Pei Yang +23
The polarization of fast radio bursts (FRBs), bright astronomical transients, contains crucial information about their environments. We report polarization measurements of five rep…
The spins of compact objects born from helium stars in binary systems
Jim Fuller, Wenbin Lu
The angular momentum (AM) content of massive stellar cores helps to determine the natal spin rates of neutron stars and black holes. Asteroseismic measurements of low-mass stars ha…
Hydrodynamics of Collisions and Close Encounters between Stellar Black Holes and Main-sequence Stars
Kyle Kremer, James C. Lombardi, Wenbin Lu +2
Recent analyses have shown that close encounters between stars and stellar black holes occur frequently in dense star clusters. Depending upon the distance at closest approach, the…
