The formation of periodic three-body orbits for Newtonian systems
Simon Portegies Zwart, Arjen Doelman, Jelmer Sein
Braids are periodic solutions to the general N-body problem in gravitational dynamics. These solutions seem special and unique, but they may result from rather usual encounters bet…
Multi-Messenger Constraints on Magnetic Fields in Merging Black Hole-Neutron Star Binaries
Daniel J. D'Orazio, Zoltan Haiman, Janna Levin +2
The LIGO-Virgo-KAGRA Collaboration recently detected gravitational waves (GWs) from the merger of black-hole-neutron-star (BHNS) binary systems GW200105 and GW200115. No coincident…
Spectral Analysis of Non-Ideal MRI Modes: The effect of Hall diffusion
Gopakumar Mohandas, Martin E. Pessah
The effect of magnetic field diffusion on the stability of accretion disks is a problem that has attracted considerable interest of late. In particular, the Hall effect has the pot…
Temperature Fluctuations driven by Magnetorotational Instability in Protoplanetary Disks
Colin P. McNally, Alexander Hubbard, Chao-Chin Yang +1
The magnetorotational instability (MRI) drives magnetized turbulence in sufficiently ionized regions of protoplanetary disks, leading to mass accretion. The dissipation of the pote…
The Stability of Weakly Collisional Plasmas with Thermal and Composition Gradients
Martin E. Pessah, Sagar Chakraborty
Over the last decade, substantial efforts have been devoted to understanding the stability properties, transport phenomena, and long-term evolution of weakly-collisional, magnetize…
