The interaction phase of engine-driven explosions and high-energy winds
Benjamin Amend, Christopher Lagomarsino, Eric R. Coughlin +1
Wide-angle outflows, or winds, are associated with a broad range of astrophysical systems, including protostars, massive stars, X-ray binaries, tidal disruption events (TDEs), lumi…
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…
On the origin of anomalous dissipation in simulations of tidal disruption events
Chris Nixon, Eric R. Coughlin, Zachary L. Andalman
In a tidal disruption event (TDE), a star is destroyed by the tidal field of a supermassive black hole. The stellar debris is initially placed on highly elliptical orbits, and a lo…
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
Brenna Mockler, Erica Hammerstein, Eric R. Coughlin +1
Stars that orbit too close to a black hole can be ripped apart by strong tides, producing a type of luminous transient event called a ``tidal disruption event" (TDE). Tidal disrupt…
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,…
