Gravitational coupling of young planets with the proto-planetary disks can give rise to spiral density waves. These spiral density waves manifest observationally in form of non-axisymmetric structures like rings, gaps and crescent like shapes. These structures may be a result of vortex formation which in turn are excited by Rossby wave instabilities. The lifetime of the vortex present in the protoplanetary disk is an important parameter in planet formation through dust entrapment and collection. There are several factors such as disk temperature, magnetic fields, disk turbulence and other instabilities which can influence vortex stability. In this work, we study the impact of thermal and viscous properties of disk on vortex lifetime through 2D hydrodynamic simulations. We introduce thermal properties in the disk through a non-isothermal process. Through these simulations, we find that the thermodynamic and viscous properties of the disk affect the vortex lifetime in a competing manner. We also explore the role of MHD driven winds in the protoplanetary disk and it’s role in planet-disk interaction. |
