Resumen

ALVAREZ-MERAZ, R.; NAGEL, E.; RENDON, F.  y  BARRAGAN, O.. Planetary Influence in the Gap of a Protoplanetary Disk: Structure Formation and an Application to V1247 Ori. Rev. mex. astron. astrofis [online]. 2017, vol.53, n.2, 00010.  Epub 21-Oct-2019. ISSN 0185-1101.

We present a set of hydrodynamical models of a planetary system embedded in a protoplanetary disk in order to extract the number of dust structures formed in the disk, their masses and sizes, within optical depth ranges τ≤0.5, 0.5 < τ<2 and τ≥2. The study of the structures shows: (1) an increase in the number of planets implies an increase in the creation rate of massive structures; (2) a lower planetary mass accretion corresponds to slower time effects for optically thin structures; (3) an increase in the number of planets allows a faster evolution of the structures in the Hill radius for the different optical depth ranges of the inner planets. An ad-hoc simulation was run using the available information of the stellar system V1247 Ori, leading to a model of a planetary system which explains the SED and is consistent with interferometric observations of structures.
