| CHR 228 |
As was the case with CHR 227, this star falls within the declination |
|
|
band missed in the surveys of Rossiter (1955) and van den Bos (1957). |
Rst1955 |
|
If physical, this 0".56 pair would presumably have an extremely long |
B__1957a |
|
period, given the spectral type and large calculated distance of its |
|
|
primary. The small change in theta seen over 2.75 years is consistent |
|
|
with this, implying a period of order 500 - 600 years. |
|
|
The star is noted in Abt & Biggs (1972) as having variable radial |
AbH1972 |
|
velocity; Hoffleit & Warren (1991) also note photometric variability |
Hof1991 |
|
of amplitude ~0.2 mag, as well as variability in the line width of |
|
|
H-alpha emission. |
