Estimating outflow masses and velocities in merger simulations: impact of r-process heating and neutrino cooling
Francois Foucart, Philipp Moesta, Teresita Ramirez +3
The determination of the mass, composition, and geometry of matter outflows in black hole-neutron star and neutron star-neutron star binaries is crucial to current efforts to model…
Electromagnetic Signatures from the Tidal Tail of a Black Hole - Neutron Star Merger
Siva Darbha, Daniel Kasen, Francois Foucart +1
Black hole - neutron star (BH-NS) mergers are a major target for ground-based gravitational wave (GW) observatories. A merger can also produce an electromagnetic counterpart (a kil…
Inclination Dependence of Kilonova Light Curves from Globally Aspherical Geometries
Siva Darbha, Daniel Kasen
The merger of two neutron stars (NSs) or a neutron star and a black hole (BH) produces a radioactively-powered transient known as a kilonova, first observed accompanying the gravit…
Ultra-deep tidal disruption events: prompt self-intersections and observables
Siva Darbha, Eric R. Coughlin, Daniel Kasen +1
A star approaching a supermassive black hole (SMBH) can be torn apart in a tidal disruption event (TDE). We examine ultra-deep TDEs, a new regime in which the disrupted debris appr…
Gravitational interactions of stars with supermassive black hole binaries. I. Tidal disruption events
Siva Darbha, Eric R. Coughlin, Daniel Kasen +1
Stars approaching supermassive black holes (SMBHs) in the centers of galaxies can be torn apart by strong tidal forces. We study the physics of tidal disruption by a binary SMBH as…
Nickel-Rich Outflows Produced by the Accretion-Induced Collapse of White Dwarfs: Lightcurves and Spectra
S. Darbha, B. D. Metzger, E. Quataert +3
The accretion-induced collapse (AIC) of a white dwarf to form a neutron star can leave behind a rotationally supported disk with mass of up to ~ 0.1 M_sun. The disk is initially co…
Electromagnetic Counterparts of Compact Object Mergers Powered by the Radioactive Decay of R-process Nuclei
B. D. Metzger, G. Martinez-Pinedo, S. Darbha +7
The most promising astrophysical sources of kHz gravitational waves (GWs) are the inspiral and merger of binary neutron star(NS)/black hole systems. Maximizing the scientific retur…
