Description

Pebble accretion process is known to be very sensitive to the initial conditions of the protoplanetary disc and a growing body of work is exploring its dependence on fundamental disc parameters (viscosity, mass, dust-to-gas). Notwithstanding this, the impact of the elemental set up of the disc, traced by the stellar composition, on the planetary occurrence rates and mass spectrum remains largely unexplored. In this talk we will present recent advancements obtained in the framework of the Ariel space mission and the GAPS and HRMOS projects on such aspects of the star-disc-planet connection.
