Abstract
We report a photometric and spectroscopic study of the hot extreme helium star LSS 5121. We found photometric variability, but no period was evident in 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.
Key words: stars: chemically peculiar / stars: oscillations / stars: variables / stars: individual: LSS 5121
Based on observations made at the University of Texas McDonald Observatory, Fort Davis, Texas and the Jacobus Kapteyn Telescope operated on the island of La Palma by the Isaac Newton Group in the Spanish Observatorio del Roque de los Muchachos of the Instituto de Astrofisica de Canarias.
