Research interests
  • Protoplanetary discs: dust-gas interaction, planet-disc interaction
  • Planet formation
  • Dynamics of accretion discs

 

Ph.D. project:

My Ph.D. project concerns the study of gas and dust dynamics in both non-self-gravitating and self-gravitating protoplanetary discs. Moreover, we want to investigate how a planet embedded in a disc interact with it. In particular, we want to put a constraint on the protoplanetary disc mass through the investigation of the behavior of the disc substructures (spirals, rings or horseshoes, originated by planet-disc interaction) by varying the coupling between the gas and the dust.

As a second aim, for the self-gravitating case, we want to study the dust trapping in spiral structures. Indeed, this mechanism could be a fundamental “catalyst” during the planetesimal formation process. 

This project will be developed by means of a theoretical/numerical approach, with a direct and continuous comparison with observational data collected mainly by the Atacama Large Millimetre/submillimetre Array (ALMA) and by the Spectro-Polarimetric High-contrast Exoplanet REsearch (SPHERE) instrument at the Very Large Telescope (VLT).
