irradiated_planet

This test case checks the evolution of an ~1 Mjup model after the surface has been irradiated.

This test case has 2 parts. Click to see a larger version of a plot.

  • Part 1 (inlist_create) loads a 1 Mjup model, relaxes the surface to an optical depth of 10, irradiates the surface with a flux of 1e7 erg cm -2 s -1 to a column depth of 1 g cm -2, and terminates when the inflated envelope reaches a surface pressure of log10 (P/(erg cm -3)) = 6.0 (about 1 bar):

  • Part 2 (inlist_evolves) continues the evolution, without irradiation, for 15 Gyr. The irradiated planet model cools and shrinks with time:
