Instability and Angular Momentum Transfer in Thick Circumbinary Disks
Allen R. Murray, Paul C. Duffell
Utilizing the DISCO code we solve the 2D hydrodynamic equations for an equal mass circular restricted binary with an isothermal circumbinary disk (CBD). This work explores the ecce…
High-Resolution Numerical Calculations of GRB Afterglow Plateaus arising from Stratified Ejecta
Paul C. Duffell, Ranadeep Ghosh Dastidar
The paper presents high‑resolution relativistic hydrodynamic simulations showing that a stratified ejecta structure can naturally produce the plateau phase observed in gamma‑ray bu…
Exploring the effect of mixing in Low-Luminosity Type IIp Supernovae by modeling SN 2024abfl
Akshith Karri, Abigail Polin, Paul Duffell
Low-luminosity Type IIp supernovae (LLSNe) are SN IIps with peak magnitudes > -15.5 and plateau magnitudes between -13.5 and -15.5 in the V band. SN 2024abfl is an LLSN with a uniq…
A Novel Parameterization for Rapid Cooling in Supernova Remnants, with applications to the Pa 30 nebula
Miranda Pikus, Paul Duffell, Soham Mandal +1
We systematically study how cooling creates structural changes in supernova remnants as they evolve. Inspired by the peculiar morphology of the Pa 30 nebula, we adopt a framework i…
Quantifying the impact of relativistic precession on tidal disruption event light curves
Diego Calderón, OndÅej Pejcha, Brian D. Metzger +2
The tidal field of a black hole can turn a star into a gas stream whose orbit can precess, especially if the a black hole is rapidly spinning. In this work, we investigate the impa…
Two-Dimensional Radiation-Hydrodynamic Simulations of Luminous Red Novae
Anthony Kirilov, Diego Calderón, OndÅej Pejcha +1
Luminous Red Novae (LRNe) are transients associated with mass ejection during stellar mergers and common envelope evolution (CEE). LRNe have the potential to illuminate the poorly…
