Abstract From 59 spectra collected at Asiago from 1969 to 1976, we obtain the spectroscopic orbit of the binary V 505 Mon. The rather long periodP=53.7805 days and semiamplitudeK 1=83±4 km s−1 of the primary component imply a fairly large mass of the secondary (m 2≥3.2±0.4m ⊙). Apparently also lines of this latter have been recorded, thus indicating highly massive components (m 1≃50,R 1=26,m 2≃27,R 2=14, in solar units) in a detached system (separation ≃255R ⊙). The already reported variation of 0.15 mag., with period about one day, together with Hα emission, we detected, point toward a possible massive X-ray progenitor.
