Effects of Planet Luminosity on Observability and Gas Dynamics
Abstract
After the opening of a gap, giant planets can keep accreting material through their circumplanetary disk. The luminosity of the accreting planet will heat its surroundings, altering the gas dynamics and its observability. Using 2D simulations we model this luminous feedback and find how the accretion of the planet becomes limited by the depletion of the circumplanetary disk, how the dynamics of the gap change with the planet luminosity, and what observable signatures can we expect from it. According to our results, a Jupiter like planet in a 10 AU orbit can be as bright as 0.001 solar luminosities, and generate Mid-Infrared signatures that would be detectable by the next generation of telescopes.
