ABSTRACT
Line identifications are presented for the peculiar Ap Si star HD 87240(δ=59° 51' 0.01") in the spectral region λλ37105520. This object is a member of the southern open cluster NGC 3114. Comparison of this object with other field silicon stars shows that it shares many of their line anomalies.
Key Words: Stars: Chemically Peculiar Stars: Individual: HD 87240
RESUMEN
Se presentan las identificaciones de las líneas de la estrella peculiar tipo Ap Si HD 87240(δ=59° 51' 0.01") en el intervalo espectral λλ37105520. Este objeto es miembro del cúmulo abierto meridional NGC 3114. La comparación de este objeto con otras estrellas Ap Si del campo muestra que tienen en común muchas de las anomalías en sus líneas.
