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…

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…

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…

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 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…
