peculiar stars

peculiar stars

Stars with spectral features that do not correspond exactly with the usual classification of spectral types. In general they are designated by a ‘p’ after their spectral type, as with Ap stars, but specific features are given other suffixes, e.g. ‘e’ for emission or ‘m’ for metallic lines.
