GRMHD Simulations of Accreting Proto-Magnetars II. Implications for r-process Nucleosynthesis
Tejas Prasanna, Kyle Parfrey, Brian D. Metzger +3
Newly formed, rapidly spinning, strongly magnetized neutron stars ("millisecond proto-magnetars") can arise in collapsars, neutron star mergers, or white-dwarf accretion-induced co…
GRMHD Simulations of Accreting Proto-Magnetars I. Implications for Gamma-Ray Burst Jets and Energetic Explosions
Tejas Prasanna, Kyle Parfrey, Brian D. Metzger +3
Newly formed, rapidly rotating, strongly magnetized neutron stars ("millisecond proto-magnetars") are promising central engines for gamma-ray bursts (GRBs) and luminous supernovae.…
Heavy element nucleosynthesis in rotating proto-magnetar winds
Tejas Prasanna, Matthew S. B. Coleman, Todd A. Thompson +3
The astrophysical origin of elements synthesized through the rapid neutron capture process (process) is a long standing mystery. The hot and dense environments of core-collapse…
Favorable conditions for heavy element nucleosynthesis in rotating proto-magnetar winds
Tejas Prasanna, Matthew S. B. Coleman, Todd A. Thompson
The neutrino-driven wind cooling phase of proto-neutron stars (PNSs) follows successful supernovae. Wind models without magnetic fields or rotation fail to achieve the necessary co…
Prospects for detecting proto-neutron star rotation and spindown using supernova neutrinos
Tejas Prasanna, Todd A. Thompson, Christopher Hirata
After a successful supernova, a proto-neutron star (PNS) cools by emitting neutrinos on s timescales. Provided that there are neutrino emission `hot-spots' or `cold-sp…
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 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…
