A 1377 | Mt. Wilson spectral classes A is G5, C is B8n. | |
AB. This appears to be part of a triple system. The elements given by | ||
Wilson (1950) and by Baize (1958) are different, possibly due to the | WRH1950b | |
long period of the system. This 1975.533 separation is less than that | Baz1958 | |
derived from either ephemeris but it and the position angle are closer | ||
to Baize's values. | BLM1978 | |
