    Yes, S Dor stars, the heaviest among all stars, have very short life-
times.  So they are found in the vicinity of where they were born -- the
place of massive star formation.  Novae are old objects - so it would be
less likely they naturally aggregate.

    But, as a northerners, I would like to know the complete list of
SDOR stars, even if their variability is not confirmed.  I have once
told V1302 Aql is such, but I don't know why this star was classified
as such.
