2500 20160701171706.0 ASTROimport-657 Zorec, J. 2004 Evolutionary status of Be stars Fundamental parameters of nearly 50 field Be stars have been determined. Correcting these parameters from gravity darkening effects induced the fast rotation, we deduced the evolutionary phase of the studied stars. We show that the evolutionary phase at which appear the Be phenomenon is mass dependent: the smaller the stellar mass the elder the phase in the main sequence at which the Be phenomenon seem to appear.
