Stellar Notes
6.97 - 7.71V, about 30d, variability attributed to circumstellar dust. Possibly a binary shell star with mass exchange. | Considerable confusion between HR 5999 and 6000 particularly as to which is the variable and which the brighter. | Originally announced as HR 6000, V856 Sco is really HR 5999, the southern preceding and fainter component C of the | bright double. The error stems from interchanged photometric data in Harvard Annals 45, 197, 1901, all other early | visual and photographic estimates indicating that the S. prec. component is the fainter.
CPM with HR 6000 at 44". CD, 7.1, 11.7v, sep. 1.3".
