B is CPD-70@1185, spectrum A6IV. |
|
CHR 227 |
Ba. Worley (private communication) noted that the systematic binary |
|
|
star surveys of Rossiter (1955) and van den Bos missed the |
Rst1955 |
|
declination band -73 to -70 deg. This probably explains why this |
|
|
half-arcsecond pair remained undiscovered until now. CHR 227 |
|
|
represents a new component to the wide (63") common proper motion pair |
|
|
HR 4211-12 = DUN 99 AB, discovered by J. Dunlap in 1826 (1829) and |
Dun1829 |
|
last observed nearly 80 years ago (Dawson 1918). A 10th magnitude C |
Daw1918a |
|
component also lies some 35" from A, discovered by John Herschel in |
HJ_1847a |
|
1835, but no closer components are known. |
