Temperatures (top row) and line-of-sight velocities (bottom row, blue indicates motion toward the observer) at optical depths log(τ_Ross) = 4, 0, and −1 (from left to right) for the 5 M_⊙ model st35gm04n045. At points with an optical depths lower than the nominal value, the value at the rear boundary is plotted. The signature of the cool material causing the dark horizontal patch developing on the lower hemisphere is visible around y = −400 R_⊙, z = 0 at log(τ_Ross) = 0 and -1. The view (axes y and z) corresponds to the intensity maps in Fig. 2.
