Total power density (panels a, b), which is the sum of the electron power density (panels c, d), the solar wind proton power density (panels e, f), and the cometary water ion power density (panels g, h). We show cuts for the y = 0 and z = 0 planes around the comet at 1.5 AU during weakly ionizing solar conditions. Red (E ⋅ J > 0) is where the electromagnetic field exerts work on charged particles, while blue (E ⋅ J < 0) shows the opposite. The comet nucleus is marked by black crosshairs. The local geometry for each row of panels is shown to the right of the figure.
