Abstract:
HR 3040 (HD 63589) exhibits pseudo-luminosity effects similar to many a main-sequence Am star, especially a strong Sr II 4077 line indicating a higher luminosity class. Its K-line matches that of A3 V, violet and blue metallic line spectrum resembles F2 III-IV, whereas its Sr II 4077 is as strong as that in an F5 III standard. With respect to its observed spectral characteristics and estimated orbital parameters, the position of HR 3040 vis-a-vis similar Am systems on the HR diagram is discussed.
