Notes. “W–Λ” corresponds to our reference case. Hmax: maximum extension reached by the post-shock medium; τcycle: cycle duration; “Window”: fixed rigid non-porous transparent interface; Λ: optically thin radiative cooling; : one solar luminosity enters the simulation box from the inner boundary; Modified Saha: Brown (1973).
