11. Mass Feeding and Feedback in Young Stellar Objects
... Ever wonder how solar-mass stars form?. ... In order for material to accrete onto a protostar it has to lose angular momentum. The angular momentum of a large natal cloud leads to the formation of a circumstellar disk and inner accretion disk as the cloud collapses. ... Winds generated in the inner disk or close to the stellar surface (we don't know which) expel material along the disk rotation axis. ... This provides the highest resolution observational data on nearby young stars. ...
