Abstract
Some LBV’s undergo brightness variations in the visual of about 1–2 magnitudes on time-scales of decades. These outbursts occur at approximately constant bolometric luminosity with the stellar radius and the temperature changing correspondingly. This subgroup of the LBV’s is generally called Hubble-Sandage variables or S Doradus stars and will be the focus of this talk. We present self-consistent radiation-hydrodynamic calculations to model the observations from minimum to maximum states.
