Spectroscopic monitoring of 141 southern field B‐type stars, 114 of them known to exhibit the Be phenomenon, allowed the estimation of their projected rotational velocities, effective temperatures and superficial gravities from both line and equivalent width fitting procedures. Stellar ages, masses and bolometric luminosities were derived from internal structure models. Without taking into account the effects of gravity darkening, we note the occurrence of the Be phenomenon in later stages of main‐sequence phase.
