Variability type BE (from B/gcvs/vartype.txt)

BE  It becomes more and more clear that, although the majority of Be
       stars are photometrically variable, not all of them could be
       properly called GCAS variables.  Quite a number of them show
       small-scale variations not necessarily related to shell events; in
       some cases the variations are quasi-periodic.  By now we are not
       able to present an elaborated system of classification for Be
       variables, but we adopt a decision that in the cases when a Be
       variable cannot be readily described as a GCAS star we give simply
       BE for the type of variability.
