I'm reading material that is seemingly contradictory. Some sources indicate that the evolution of a protostar to a main sequence star is characterised by a stellar wind that precludes the accretion of further in-falling material. That is, the (young) star now has a constant mass. However, other sources suggest that material may continue to accrete for a (brief) period after the protostar has become a main sequence star.
Can someone please confirm the actual process?
