Protoplanetary discs as probes of star formation: the Orion Nebula Cluster
Andrew Winter UoL, Leicester, UK | |
| Mounting evidence suggests that the process of planet formation is strongly dependent on the birth environment of the host star. Due to the stellar feedback of stars on PPDs, the properties of the latter are in principle a probe of star formation processes. I first illustrate the observational evidence for environmentally induced PPD depletion in Cygnus OB2 and sigma Orionis. I then discuss the Orion Nebula Cluster, and how careful dynamical considerations can help to solve the long standing 'proplyd lifetime problem'. This modelling process yields new insights into the star formation history and dynamical evolution of the region. Hence, PPDs may be used as a tool for understanding the earliest stages of stellar clusters. | |
