The Maximum Gravity Model for partial Tidal Disruption Events: Mass Loss, Peak Fallback Rate and Dependence on Stellar Properties
Ananya Bandopadhyay, Eric R. Coughlin, C. J. Nixon
A star entering the tidal sphere of a supermassive black hole (SMBH) can be partially stripped of mass, resulting in a partial tidal disruption event (TDE). Here we develop an anal…
Resolving the (Debate About) Nozzle Shocks in Tidal Disruption Events
Zachary L. Andalman, Eliot Quataert, Eric R. Coughlin +1
When a star passes within the Roche limit of a supermassive black hole (SMBH), it is pulled apart by the BH's tidal field in a tidal disruption event (TDE). The resulting flare is…
Tidal disruption events with SPH-EXA: resolving the return of the stream
Noah Kubli, Alessia Franchini, Eric R. Coughlin +4
In a tidal disruption event (TDE), a star is disrupted by the tidal field of a massive black hole, creating a debris stream that returns to the black hole, forms an accretion flow,…
Predicting the Properties of the Fallback Rate from Tidal Disruption Events: Investigating the Maximum Gravity Model
Julia Fancher, Ananya Bandopadhyay, Eric R. Coughlin +1
A star destroyed by the tidal field of a supermassive black hole (SMBH) in a tidal disruption event (TDE) gives rise to a luminous flare. TDEs are being detected at an ever-increas…
Repeated Tidal Interactions between Stars and Supermassive Black Holes: Mass Transfer, Stability, and Implications for Repeating Partial Tidal Disruption Events
Ananya Bandopadhyay, Eric R. Coughlin, C. J. Nixon
Stars orbiting supermassive black holes can generate recurring accretion flares in repeating partial tidal disruption events (TDEs). Here we develop an efficient formalism for anal…
What's kickin' in partial tidal disruption events?
Eric R. Coughlin, C. J. Nixon
Stars partially destroyed by a supermassive black hole (SMBH) in a partial tidal disruption event (TDE) can be ejected from the SMBH. Previous investigations attributed this positi…
Repeated Partial Tidal Disruptions and Quasi-Periodic Eruptions in SwJ023017.0+283603
Dheeraj Pasham, Eric Coughlin, Chris Nixon +5
SwJ023017.0+283603 (SwJ0230) exhibited soft X-ray (0.3-1.0 keV) eruptions recurring roughly every 22 days. We present results from an extended monitoring campaign of SwJ0230 using…
A Potential Second Shutoff from AT2018fyk: An updated Orbital Ephemeris of the Surviving Star under the Repeating Partial Tidal Disruption Event Paradigm
Dheeraj Pasham, Eric Coughlin, Muryel Guolo +4
The tidal disruption event (TDE) AT2018dyk/ASASSN-18UL showed a rapid dimming event 500 days after discovery, followed by a re-brightening roughly 700 days later. It has been hypot…
Repeating nuclear transients from repeating partial tidal disruption events: reproducing ASASSN-14ko and AT2020vdq
Ananya Bandopadhyay, Eric R. Coughlin, C. J. Nixon +1
Some electromagnetic outbursts from the nuclei of distant galaxies have been found to repeat on months-to-years timescales, and each of these sources can putatively arise from the…
Ultra-deep cover: an exotic and jetted tidal disruption event candidate disguised as a gamma-ray burst
R. A. J. Eyles-Ferris, C. J. Nixon, E. R. Coughlin +1
Gamma-ray bursts (GRBs) are traditionally classified as either short GRBs with durations s that are powered by compact object mergers, or long GRBs with durations $\gt…
Alive but Barely Kicking: News from 3+ years of Swift and XMM-Newton X-ray Monitoring of Quasi-Periodic Eruptions from eRO-QPE1
Dheeraj R. Pasham, Eric R. Coughlin, Michal Zajacek +11
Quasi-periodic Eruptions (QPEs) represent a novel class of extragalactic X-ray transients that are known to repeat at roughly regular intervals of a few hours to days. Their underl…
Lense-Thirring Precession after a Supermassive Black Hole Disrupts a Star
Dheeraj R. Pasham, Michal Zajacek, C. J. Nixon +8
An accretion disk formed around a supermassive black hole (SMBH) after it disrupts a star is expected to be initially misaligned with respect to the black hole's equatorial plane.…
