WebA circumplanetary disc with a dead zone. 2823. satellites is analogous to planet formation, then satellitesimals could form in the same way in a circumplanetary disc. We note that if the dead zone viscosity is sufficiently small, however, a steady-state disc may not exist (Martin & Lubow 2014). Circumplanetary discs with dead zones may be ... WebOct 1, 2010 · For a circumplanetary disk viscosity parameter α ∼ 10 −3 and a final planet contraction timescale ⩾10 7 yr (corresponding approximately to a planet opacity ⩾10 −2 cm 2 g −1), peak gas surface densities in the circumplanetary disk throughout most of its history are ∼10 2 –10 3 g cm −2.
