DESCRIPTION:Speakers: Alexandros Ziampras (University of Tuebingen)\nRecen
 t ALMA observations revealed concentric annular structures in several youn
 g\, class-II objects. Some have been modeled numerically with a single emb
 edded planet assuming a locally isothermal equation of state\, a method of
 ten used in the irradiation-dominated outer disk regions. We compare local
 ly isothermal and radiative disks similar to HD 163296 and AS 209 with emb
 edded planets and\nshow that the disk thermodynamics can impact the number
  of rings and the contrast of spirals produced by a planet. Radiative effe
 cts can suppress features visible in locally isothermal simulations. These
  results suggest the need for multiple planets to explain the ring-rich st
 ructures in such systems.\n\nhttps://meetings.aip.de/event/1/contributions
