RESUMEN
Presentamos la identificación de líneas del espectro de la estrella Bp de Hg–Mn HD 53244 (γCMa) en el intervalo espectral λλ3700 – 6700 Å. Este objeto es miembro del cúmulo abierto austral Cr 121. La comparación de su espectro con otros de estrellas de Hg–Mn de campo muestra que comparte muchas de las anomalías espectrales pero también presenta algunas diferencias.
ABSTRACT
Line identifications are presented for the Hg–Mn Bp star HD 53244 (γCMa), in the spectral region λλ3750 — 6700 Å. This object is a member of the southern open cluster Cr 121. Comparison of the spectrum of HD 53244 with other field Hg–Mn stars shows that it shares many of their spectral anomalies but that also some differences exist.
Key Words: stars: chemically peculiar — stars: line identification — stars: individual (HD 53244).
