Abstract
We report a photometric and spectroscopic study of the hot extreme helium s tar LSS 5121. We found photometric variability, but no period was evident i n its periodogram. This is consistent with the previous proposal, based on spectral line variations, that LSS 5121 is a non-radial pulsator similar to other hot extreme helium stars.
