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…
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…
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 Antesonic Condition for the Explosion of Core-Collapse Supernovae II: Rotation and Turbulence
Matthias J. Raives, Todd A. Thompson, Sean M. Couch
In the problem of steady free-fall onto a standing shockwave around acentral mass, the "antesonic" condition limits the regime of stable accretion to $c_T^2/v_\mathrm{esc}^2\leq3/1…
The Antesonic Condition for the Explosion of Core-Collapse Supernovae I: Spherically Symmetric Polytropic Models: Stability & Wind Emergence
Matthias J. Raives, Sean M. Couch, Johnny P. Greco +2
Shock revival in core-collapse supernovae (CCSNe) may be due to the neutrino mechanism. While it is known that in a neutrino-powered CCSN, explosion begins when the neutrino lumino…
Accurate, Meshless Methods for Magneto-Hydrodynamics
Philip F. Hopkins, Matthias J. Raives
Recently, we developed a pair of meshless finite-volume Lagrangian methods for hydrodynamics: the 'meshless finite mass' (MFM) and 'meshless finite volume' (MFV) methods. These cap…
