  Spectroscopic monitoring of 141 southern &#64257;eld B type stars, 114 of
them known to exhibit the Be phenomenon, allowed the estimation of their
projected rotational velocities, effective temperatures and super&#64257;cial
gravities from both line and equivalent width &#64257;tting procedures. Stellar
ages, masses and bolometric luminosities were derived from internal structure
models. Without taking into account for the effects of gravity darkening, we
notice the occurrence of the Be phenomenon in later stages of main sequence
phase.
