| Summary: | There are many protoplanetary disks that have been well resolved observationally in various wavelengths. HL Tau system is an excellent example of them. HL Tau is a young star located in the transition of class I to class II in Young Stellar Object (YSO) classification based on its Stellar Energy Distribution (SED). More recently, long-baseline observations at wavelenghts of sub-mm to mm using Atacama Large Millimetre / Submillimetre Array (ALMA) have been able to obtain a pristine images and show gaps on HL Tau. They formed seven pairs of dark and bright ring structure. The gaps are associated to the formation of planets in the system. <br />

In this final project, We present eight models of protoplanetary disk with three non-accreting planets and two models with three accreting planets to study their evolution after 500th orbit of the inner planet. The models used FARGO-2D1D with two variations of the disk kinematic viscosity, i.e. 10−5 and 10−3. The planet masses are 0.2, 0.27, and 0.55 MJ at distance 13.2, 32.3 and 68.8 au. The models with non-accreting planets provide dark-bright structure on the protoplanetary disk after the 100th orbit of the inner planet. The structure resembles dark-light ring pairs on HL Tau based on ALMA observation, but with different density contrast. We also found planetary migration phenomenons in our models. |
