A Transport Theory of Turbulent Coronal Heating in General Geometry
Jonathan Squire, Benjamin D. G. Chandran, Toby Adkins +3
Magnetic geometry shapes how turbulence transports and dissipates energy in strongly magnetized plasmas. The solar corona, a maze of open and closed flux tubes with sharp transvers…
Global Simulations of Gravitational Instability in Protostellar Disks with Full Radiation Transport II. Locality of Gravitoturbulence, Clumpy Spirals, and Implications for Observable Substructure
Wenrui Xu, Yan-Fei Jiang, Matthew W. Kunz +1
Spiral perturbations in a gravitationally unstable accretion disk regulate disk evolution through angular-momentum transport and heating and provide an observational signature of g…
Global Simulations of Gravitational Instability in Protostellar Disks with Full Radiation Transport. I. Stochastic Fragmentation with Optical-depth-dependent Rate and Universal Fragment Mass
Wenrui Xu, Yan-Fei Jiang, Matthew W. Kunz +1
Fragmentation in a gravitationally unstable accretion disk can be an important pathway for forming stellar/planetary companions. To characterize quantitatively the condition for an…
Tearing-mediated reconnection in magnetohydrodynamic poorly ionized plasmas. I. Onset and linear evolution
Elizabeth A. Tolman, Matthew W. Kunz, James M. Stone +1
In high-Lundquist-number plasmas, reconnection proceeds via onset of tearing, followed by a nonlinear phase during which plasmoids continuously form, merge, and are ejected from th…
Extreme Plasma Astrophysics
D. Uzdensky, M. Begelman, A. Beloborodov +22
This is a science white paper submitted to the Astro-2020 and Plasma-2020 Decadal Surveys. The paper describes the present status and emerging opportunities in Extreme Plasma Astro…
Multi-Species Measurements of the Firehose and Mirror Instability Thresholds in the Solar Wind
C. H. K. Chen, L. Matteini, A. A. Schekochihin +5
The firehose and mirror instabilities are thought to arise in a variety of space and astrophysical plasmas, constraining the pressure anisotropies and drifts between particle speci…
