The Role of the Magnetorotational Instability in Massive Stars
J. Craig Wheeler, Daniel Kagan, Emmanouil Chatzopoulos
The magnetorotational instability (MRI) is key physics in accretion disks and is widely considered to play some role in massive-star core collapse. Models of rotating massive stars…
Finding the First Cosmic Explosions. IV. 90 - 140 M Pair-Instability Supernovae
Joseph Smidt, Daniel J. Whalen, E. Chatzopoulos +4
Population III stars that die as pair-instability supernovae are usually thought to fall in the mass range of 140 - 260 M. But several lines of work have now shown that r…
Characterizing the Velocity Fields in Massive Stars
Emmanouil Chatzopoulos, Carlo Graziani, Sean M. Couch
We apply the mathematical formalism of vector spherical harmonics decomposition to convective stellar velocity fields from multi-dimensional hydrodynamics simulations, and show tha…
