Electron acceleration in non-relativistic quasi-perpendicular collisionless shocks
Rui Xu, Anatoly Spitkovsky, Damiano Caprioli
We study diffusive shock acceleration (DSA) of electrons in non-relativistic quasi-perpendicular shocks using self-consistent one-dimensional particle-in-cell (PIC) simulations. By…
Chemical network reduction in protoplanetary disks
Rui Xu, Xue-Ning Bai, Karin Öberg +1
Protoplanetary disks (PPDs) are characterized by different kinds of gas dynamics and chemistry, which are coupled via ionization, heating and cooling processes, as well as advectiv…
Turbulent-diffusion Mediated CO Depletion in Weakly Turbulent Protoplanetary disks
Rui Xu, Xue-Ning Bai, Karin Oberg
Volatiles, especially CO, are important gas tracers of protoplanetary disks (PPDs). Freeze-out and sublimation processes determine their division between gas and solid phases, whic…
Linear Vlasov theory of a magnetised, thermally stratified atmosphere
Rui Xu, Matthew W. Kunz
The stability of a collisionless, magnetised plasma to local convective disturbances is examined, with a focus on kinetic and finite-Larmor-radius effects. Specific application is…
On the Grain-Modified Magnetic Diffusivities in Protoplanetary Disks
Rui Xu, Xue-Ning Bai
Weakly ionized protoplanetary disks (PPDs) are subject to non-ideal-magnetohydrodynamic (MHD) effects including Ohmic resistivity, the Hall effect and ambipolar diffusion (AD), and…
