Fig. 5: Disk structure at the midplane formed by an impact between icy planets (MT = 1M⊕, γ = 0.13, θ = 48. 5∘, vimp = vesc, Run ID20).

The line descriptions are the same as those in Fig. 4. The panels show (a) the surface density, (b) temperature, (c) vapor mass fraction, and (d) pressure gradient parameter η as a function of r/R⊕. The planetary radius is 1.42 R⊕.
