The early evolution of magnetar rotation -- II. Rapidly rotating magnetars: Implications for Gamma-Ray Bursts and Super Luminous Supernovae
Tejas Prasanna, Matthew S. B. Coleman, Matthias J. Raives +1
Rapidly rotating magnetars have been associated with gamma-ray bursts (GRBs) and super-luminous supernovae (SLSNe). Using a suite of 2D magnetohydrodynamic simulations at fixed neu…
The Gravitational-Wave Signature of Core-Collapse Supernovae
David Vartanyan, Adam Burrows, Tianshu Wang +2
We calculate the gravitational-wave (GW) signatures of detailed 3D core-collapse supernova simulations spanning a range of massive stars. Most of the simulations are carried out to…
Magnetized Rotating Isothermal Winds
Matthias J. Raives, Matthew S. B. Coleman, Todd A. Thompson
We consider the general problem of a Parker-type non-relativistic isothermal wind from a rotating and magnetic star. Using the magnetohydrodynamics (MHD) code athena++, we construc…
Kicks and Induced Spins of Neutron Stars at Birth
Matthew S. B. Coleman, Adam Burrows
Using simulations of non-rotating supernova progenitors, we explore the kicks imparted to and the spins induced in the compact objects birthed in core collapse. We find that the re…
The Early Evolution of Magnetar Rotation I: Slowly Rotating "Normal" Magnetars
Tejas Prasanna, Matthew S. B. Coleman, Matthias J. Raives +1
In the seconds following their formation in core-collapse supernovae, "proto"-magnetars drive neutrino-heated magneto-centrifugal winds. Using a suite of two-dimensional axisymmetr…
The Essential Character of the Neutrino Mechanism of Core-Collapse Supernova Explosions
Tianshu Wang, David Vartanyan, Adam Burrows +1
Calibrating with detailed 2D core-collapse supernova simulations, we derive a simple core-collapse supernova explosion condition based solely upon the terminal density profiles of…
On the Origin of Pulsar and Magnetar Magnetic Fields
Christopher J. White, Adam Burrows, Matthew S. B. Coleman +1
In order to address the generation of neutron star magnetic fields, with particular focus on the dichotomy between magnetars and radio pulsars, we consider the properties of dynamo…
Boundary Layers of Accretion Disks: Wave-Driven Transport and Disk Evolution
Matthew S. B. Coleman, Roman R. Rafikov, Alexander A. Philippov
Astrophysical objects possessing a material surface (white dwarfs, young stars, etc.) may accrete gas from the disc through the so-called surface boundary layer (BL), in which the…
The Physical Effects of Progenitor Rotation: Comparing Two Long-Duration 3D Core-Collapse Supernova Simulations
Matthew S. B. Coleman, Adam Burrows, Christopher J. White
We analyse and determine the effects of modest progenitor rotation in the context of core-collapse supernovae by comparing two separate long-duration three-dimensional simulations…
The Collapse and Three-Dimensional Explosion of Three-Dimensional, vis à vis One-Dimensional, Massive-star Supernova Progenitor Models
David Vartanyan, Matthew S. B. Coleman, Adam Burrows
The explosion outcome and diagnostics of core-collapse supernovae depend sensitively on the nature of the stellar progenitor, but most studies to date have focused exclusively on o…
Boundary Layers of Accretion Disks: Discovery of Vortex-Driven Modes and Other Waves
Matthew S. B. Coleman, Roman R. Rafikov, Alexander A. Philippov
Disk accretion onto weakly magnetized objects possessing a material surface must proceed via the so-called boundary layer (BL) - a region at the inner edge of the disk, in which th…
An Extension of the Athena++ Framework for General Equations of State
Matthew S. B. Coleman
We present modifications to the Athena++ framework to enable use of general equations of state (EOS). Part of our motivation for doing so is to model transient astrophysics phenome…
Gravitational-wave-moderated Accretion: The Case of ES Ceti
Matthew S. B. Coleman, Tejaswi Venumadhav, Barak Zackay
We show that recent observations of the compact binary, AM CVn type system, ES Ceti are fully consistent with theoretical predictions of stable mass transfer moderated by angular m…
Solving the Riemann Problem for Realistic Astrophysical Fluids
Zhuo Chen, Matthew S. B. Coleman, Eric G. Blackman +1
We present new methods to solve the Riemann problem both exactly and approximately for general equations of state (EoS) to facilitate realistic modeling and understanding of astrop…
Convection Enhances Magnetic Turbulence in AM CVn Accretion Disks
Matthew S. B. Coleman, Omer Blaes, Shigenobu Hirose +1
We present the results of local, vertically stratified, radiation magnetohydrodynamic shearing box simulations of magnetorotational instability (MRI) turbulence for a (hydrogen poo…
Convective Quenching of Field Reversals in Accretion Disc Dynamos
Matthew S. B. Coleman, Evan Yerger, Omer Blaes +2
Vertically stratified shearing box simulations of magnetorotational turbulence commonly exhibit a so-called butterfly diagram of quasi-periodic azimuthal field reversals. However,…
Dwarf Nova Outbursts with Magnetorotational Turbulence
M. S. B. Coleman, I. Kotko, O. Blaes +2
The phenomenological Disc Instability Model has been successful in reproducing the observed light curves of dwarf nova outbursts by invoking an enhanced Shakura-Sunyaev paramet…
Convection Causes Enhanced Magnetic Turbulence in Accretion Disks in Outburst
Shigenobu Hirose, Omer Blaes, Julian H. Krolik +2
We present the results of local, vertically stratified, radiation MHD shearing box simulations of MRI turbulence appropriate for the hydrogen ionizing regime of dwarf nova and soft…
Substructure in Dwarf Galaxies
Matthew Coleman
Recent years have seen a series of large-scale photometric surveys with the aim of detecting substructure in nearby dwarf galaxies. Some of these objects display a varying distribu…
