DUN 252 alp 1 Cru = Acrux. According to R.G. Aitken, this was discovered by A__1935f
the Jesuit missionary, Father Fontenay, at the Cape of Good Hope, in Fon1733
1685, although the triple was first measured by Dunlop and called Dun1829
DUN 123AB and DUN 122AC. Spectroscopic binary. CPM with HR 4729 and
HR 4731, so there are at least five components in the system.
Hyperbolic orbit by Hopmann (1960). Hop1960b
q = periastron distance in the true orbit = 0".916
Both A and B appear to be spectroscopic binaries with undetermined Bte1967
periods (see Batten 1967). Fin1970b
