Abstract

The disc planet interaction and planetary formation in accretion discs have become a topic of renewed interest in the last decade, encouraged by the discovery of extra-solar planets, and in particular of hot Jupiters. Recent long-baseline ALMA (Atacama Large Millimeter Array) observations revealed a striking pattern of bright and dark rings in the protoplanetary disc surrounding the young star HL Tau. Our group has provided one of the earliest explanations of this system in terms of the interaction of the disc with three newly born planets (Dipierro et al, MNRAS 453, L73–L77, 2015) [6]. The aim of this study is to develop a new model for gas and dust distribution within this disc. This work is focused on identifying the mass of the planets able to carve gaps in HL Tau, in the three main ring-like structures observed by ALMA.
