HR 6046 has long been known as a single-lined binary with a late-K-giant primary star. The long period of just over six years and the large mass function led to several, so far unsuccessful, attempts to resolve the system interferometrically. However, we have detected the secondary spectroscopically, and present here the spectroscopic orbital elements. The secondary is nearly as massive as the primary, despite being much fainter. Comparison with late-type standard spectra suggests that it is also an evolved star.

Resumen

Resumen

HR 6046 se conoce desde hace mucho como una binaria espectroscópica de una línea, cuya primaria es de tipo K tardío. El largo período (de más de seis años) y el alto valor de la función de masa han motivado varios intentos, hasta ahora fallidos, para resolver interferométricamente el sistema. Sin embargo, hemos detectado espectroscópicamente a la secundaria, y presentamos aquí los elementos orbitales espectroscópicos. La secundaria tiene una masa casi igual a la de la primaria, pese a que es mucho más débil. La comparación con espectros estándar para tipos tardíos sugiere que también la secundaria es una estrella evolucionada.
