MCA 75 | psi And = 20 And. R.H. Wilson reported a wide, faint companion. | WRH1950a |
H. McAlister resolved the primary into a triple system. | McA1978b | |
Aac: It is not established whether this third component belongs to Aa | ||
or Ab. | ||
Based on mean motion of Aa,Ac a period of ~300 years is postulated. | Tok2010b | |
Based on the separation of Aa,Ab relative to this dynamic stability | ||
is questioned, however Aa,Ab has only been measured four times while | ||
Aa,Ac has been measured 39. Is Aa,Ab of a larger delta-m and if not | ||
why is it so infrequently measured. Could it be spurious? |
