Three-dimensional rendering of the bow shock for the (a) laminar and (b) turbulent solar wind cases. Ion density is represented in blue hues. A threshold density of n_th = 10^1/4n₀ is applied, such that all regions in which n_i < n_th are made transparent. A linear transparency profile is applied from n_i = n_th to n_i = 6n₀, and so low-density regions are more transparent than high-density ones. Upstream magnetic field lines crossing the ion foreshock regions are drawn in red.
