| Abstract: |
We present period determinations of the microvariability of six Luminous Blue Variables. We determined 22 periods ranging from 22 to 227 days. The Q-values are significantly larger than expected for the radial fundamental mode. Q changes considerably from one epoch to another. We attempted mode identifications based on a simple pulsation model by means of multicolour Stromgren photometry and find that none of the microvariations can be explained by radial pulsations. |
