Query: Role of electron inertia and electron/ion finite Larmor radius effects
  in low-beta, magneto-Rayleigh-Taylor instability   The magneto-Rayleigh-Taylor (MRT) instability has been investigated in great
detail in previous work using magnetohydrodynamic and kinetic models for
low-beta plasmas. The work presented here extends previous studies of this
instability to regimes where finite-Larmor-Radius (FLR) effects may be
important. Comparisons of the MRT instability are made using a 5-moment and a
10-moment two-fluid model, the two fluids being ions and electrons. The
5-moment model includes Hall stabilization whereas the 10-moment model includes
Hall and FLR stabilization. Results are presented for these two models using
different electron mass to understand the role of electron inertia in the
late-time nonlinear evolution of the MRT instability. For the 5-moment model,
the late-time nonlinear MRT evolution does not significantly depend on the
electron inertia. However, when FLR stabilization is important, the 10-moment
results show that a lower ion-to-electron mass ratio (i.e. larger electron
inertia) under-predicts the energy in high-wavenumber modes due to larger FLR
stabilization.
