The evolution of protoplanetary discs in star formation and feedback simulations

ABSTRACT We couple star cluster formation and feedback simulations of a Carina-like star-forming region with 1D disc evolutionary models to study the impact of external photoevaporation on disc populations in massive star-forming regions. To investigate the effect of shielding of young stellar objec...

Description
Summary:ABSTRACT We couple star cluster formation and feedback simulations of a Carina-like star-forming region with 1D disc evolutionary models to study the impact of external photoevaporation on disc populations in massive star-forming regions. To investigate the effect of shielding of young stellar objects by star-forming material, we track the far-ultraviolet (FUV) field history at each star in the cluster with two methods: (i) Monte Carlo radiative transfer accounting for the shielding of stars from the FUV by the star-forming cloud and (ii) geometric dilution of the radiation from other stars, which ignores shielding effects. We found that significant shielding only occurs for a small fraction of discs and offers protection from external photoevaporation for
