Super-Eddington Chimneys: On the Cooling Evolution of Tidal Disruption Event Envelopes
Semih Tuna, Brian D. Metzger, Yan-Fei Jiang +1
The formation of a compact accretion disk following a tidal disruption event (TDE) requires that the shocked stellar debris cool efficiently as it settles toward the black hole. Wh…
Dynamical binary interactions in the 2040s
Nadejda Blagorodnova, Ondřej Pejcha, Tomek Kamiński +15
Dynamical binary interactions such as common envelope (CE) evolution or stellar mergers are a critical phase in the formation of a wide variety of binary phenomena, ranging from bl…
Tidal disruption event Calorimetry: Observational constraints on the physics of TDE optical flares
Andrew Mummery, Brian Metzger, Sjoert van Velzen +1
Tidal disruption events are routinely discovered as bright optical/UV flares, the properties of which are now well categorized on the population level. The underlying physical proc…
EP241217a: a likely Type II GRB with an achromatic bump at z = 4.59
Hao Zhou, Jia Ren, Chen-Wei Wang +22
EP241217a is an X-ray transient detected by the Einstein Probe (EP) lasting for about 100 seconds and without accompanying -ray detection. The optical spectroscopy reveals the r…
Multiple outflows and delayed ejections revealed by early imaging of novae
Elias Aydi, John D. Monnier, Antoine Mérand +39
Novae are thermonuclear eruptions on accreting white dwarfs in interacting binaries. Although most of the accreted envelope is expelled, the mechanism -- impulsive ejection, multip…
Luminous Fast Blue Optical Transients as "Failed" Gravitational-wave Sources: Helium CoreBlack Hole Mergers Following Delayed Dynamical Instability
Jakub Klencki, Brian D. Metzger
Binaries in which a massive donor star undergoes an extended ( kyr) phase of stable mass transfer onto a black hole (BH) accretor offer a promising channel for creating LI…
No Sign of a Magnetar Remnant Following the Kilonova-Producing Long GRB 211211A Years Later
Genevieve Schroeder, Ben Margalit, Brian D. Metzger +9
In addition to a -ray burst (GRB), the merger of two neutron stars may produce a temporarily or indefinitely stable neutron star remnant with a strong magnetic field (a "magneta…
Jet-driven explosion of an accretion-induced white-dwarf collapse via a magnetorotational dynamo
Luciano Combi, Daniel M. Siegel, Brian D. Metzger
The accretion-induced collapse (AIC) of a rotating white dwarf (WD) offers a potential site of millisecond pulsars/magnetars, gamma-ray bursts, and r-process nucleosynthesis. We pr…
Gravitational Instability and Fragmentation in Collapsar Disks Supports the Formation of Sub-Solar Neutron Stars
Yi-Xian Chen, Brian D. Metzger
We perform three-dimensional shearing-box hydrodynamical simulations to explore the outcome of gravitational instability in the outer regions of neutrino-cooled disks such as those…
Suppression of Shock X-ray Emission in Novae from Turbulent Mixing with Cool Gas
Brian D. Metzger, Lachlan Lancaster, Rebecca Diesing
Shock interaction in classical novae occurs when a fast outflow from the white dwarf > 1000 km s/s collides with a slower, cooler shell of gas released earlier in the outburst. The…
QPEs from EMRI Debris Streams Impacting Accretion Disks in Galactic Nuclei
Itai Linial, Brian D. Metzger, Eliot Quataert
Quasi-periodic eruption (QPE) sources in galactic nuclei are often associated with a stellar object orbiting a supermassive black hole with hours-days period, brought in as an extr…
Ignition of weak interactions and r-process outflows in super-collapsar accretion disks
Aman Agarwal, Daniel M. Siegel, Brian D. Metzger +1
The collapse of rotating massive (~) stars resulting in hyperaccreting black holes (BHs; "collapsars") is a leading model for the central engines of long-duration gamma…
Time-Dependent Radiation Transport Simulations of Infrared Echoes from Dust-Shrouded Luminous Transients
Semih Tuna, Brian D. Metzger, Yan-Fei Jiang +1
A wide range of stellar explosions, including supernovae (SNe), tidal disruption events (TDE), and fast blue optical transients (FBOT), can occur in dusty environments initially op…
