| Abstract: |
In 1984 Conti grouped together the P Cygni, Hubble-Sandagei and S Dor
variable stars into a new class the Luminous Blue Variables (LBVs).
His unification was based on the fact that the underlying mechanism
for the variability and the stars parameters are similar and the
only difference that remained seemed the host galaxy. A significant
subset of LBVs is known to be surrounded by circumstellar nebulae.
A characterization of the present known set of LBVs in the Local Volume
will be given as well as a categorization of their evolutionary status.
In particular I will address LBVs with nebulae and discuss what we
learn from morphologies and kinematics of the nebulae about parameters
and possible instabilities of the stars. |
