Scientific paper

High-resolution spectra of the southern Galactic sdO star KS 292 are analyzed using modern NLTE model atmospheres in order to determine the atmospheric parameters. The results indicate that KS 292 probably belongs to a newly discovered group of post-AGB stars which are characterized by effective temperatures and gravities typical for central stars of planetary nebulae but which apparently lack circumstellar nebulae.
