Two summaries of the dimensionless time rates of change of the ion total temperature (red squares) and the electron total temperature (blue dots) as functions of the initial magnetic fluctuation energy density of the four kinetic Alfvén turbulence simulations. (a) The maximum values of Q_iand Q_e. The blue dashed line represents Q_e = 0.001ε_o (Equation (3) of Hughes et al. 2017), the approximate scaling for maximum electron heating due to whistler turbulence at β_e = 0.50. (b) The rates of change of the ion and electron total temperatures averaged over the simulation times between ω_pet = 25.6 and 512.0.
