If you have a question about this talk, please contact Dr. Yufeng Lin. Recently, younger and younger planets were detected, often still embedded in gaseous circumstellar disks. In this evolutionary phase, giant planets are still accreting from their own disk, the circumplanetary disk. This disk is the key to understand the late giant planet formation, the satellite formation and to unveil how we can observe forming planets and what characteristics we can derive out from the data. Even though there is no direct observation of the circumplanetary disk yet, the trace of hot gas around gas-giants has already been detected from near-infrared emission via high contrast imaging and by H-alpha emission. The race for the first firm detection is still continuing and I will present how we can detect these disks with ALMA . In my talk, I will summarize what we learned about giant planet accretion and satellite formation from the newest radiative hydrodynamic simulations, and how the circumplanetary disk influences the entropy of the gas giant, making the “hot-start” versus “cold-start” debate even more complicated.
