Disco in the Dust: Reflected light at the bow shock around Betelgeuse's companion explains its observed luminosity
Jared A. Goldberg, Meridith Joyce, Anna J. G. O'Grady +6
Recent detections of Orionis B, the putative companion to Betelgeuse, have been reported using multiple instruments and techniques. These include, most recently, a detect…
Aspherical Remnants of Triple and Quadruple Detonations in Binary White Dwarfs
Logan J. Prust, Lars Bildsten, Samuel J. Boos
White dwarfs which explode by the double-detonation mechanism may have a binary white dwarf donor which is subsequently ignited by its collision with the ejecta. This results in th…
The First 4 Years of SN 1993J Revisited: Geometric -ring Modeling of the Radio Shell with Closure Quantities Only
Joseph R. Farah, Logan J. Prust, Giacomo Terreran +5
SN 1993J is the best-studied radio supernova, with observations using very-long-baseline interferometry (VLBI) spanning from within weeks of explosion through nearly three decades…
Lense-Thirring precessing magnetar engine drives a superluminous supernova
Joseph R. Farah, Logan J. Prust, D. Andrew Howell +10
Type I superluminous supernovae (SLSNe-I) are at least an order of magnitude brighter than standard supernovae, with the internal power source for their luminosity still unknown. T…
The First Day of a Type Ia Supernova from a Double-Degenerate Binary
Gabriel Kumar, Logan J. Prust, Lars Bildsten
Supernovae in binary star systems involve a hydrodynamical interaction between the ejecta and a binary companion. This collision results in shock heating and a modified density str…
Wakes from Companion Interactions in Type Ia Supernovae Nebular Emission Line Profiles
Kathlynn Simotas, Lars Bildsten, Logan J. Prust
Thermonuclear supernovae (SNe) are the result of the nuclear transformation of carbon/oxygen (C/O) white dwarfs (WDs) to the radioactive element and intermediate…
