| Abstract: |
Luminous Blue Variables are evolved stars which experience periods of enhanced mass loss and outbursts. During these outbursts, the star stays at constant luminosity, but appears to become cooler. The S Doradus type variability, unlike the more extreme eruptions seen in
η Car, occur on timescales of years to decades. The origin of the variability is still not understood, nor is the connection to extreme objects such as η Car. In this work, we examine hydrodynamic models of radial pulsation including time-dependent convection in massive stars, looking for the conditions necessary to trigger S Doradus type variability. |
