Photometry of the extreme helium star HD 124448
Description
The extreme helium star HD 124448 has been examined for photometric variability on time-scales ranging from hours to years. There is no evidence for light variations of more than 0.02 mag. Following a similar result for BD + 1002179, the criterion for pulsational instability in hot luminous hydrogen-deficient stars appears to be the luminosity to mass ratio of the star. (author)
