2D dust temperature distribution around the circumstellar disk gap in the range 40–120 K (top). Solid, dashed, and dotted black contours indicate the relative UV field strength χ (see Eq. (12)). The white circle with black border represents the position of Jupiter and the horizontal bar indicates the physical extent of the CPD. The white cross with black border represents the location from which the inherited chemistry is extracted at one scale height z = H. Hydrogen nuclei column density (blue line) with unperturbed circumstellar disk density profile for comparison (light blue dashed line; bottom).
