DESCRIPTION:Accretion disks are the birthplace of planets. A young planet 
 interacts with its surrounding disk\, launching spiral density waves that 
 lead to the formation of rings and gaps observable with ALMA. The disk\, i
 n turn\, exerts a torque on the planet\, causing it to migrate through the
  disk. The role of radiative processes in these mechanisms has recently be
 come more important\, as our understanding of the thermodynamics improves 
 and the complexity of models increases. I will present how cooling and spe
 cifically in-plane radiative diffusion affect planet-driven gap opening\, 
 and show that models with more realistic thermodynamics can produce higher
 -quality synthetic observations of ALMA disks with substructures. I will t
 hen show how radiation transport can impact the dynamical corotation torqu
 e\, effectively accelerating or decelerating the planet's orbital evolutio
 n depending on context.
