HJ 1718 |
AB: HJ 1719 = STI2607. Burnham's note for HJ 1719 quotes Herschel as |
Bu_1906 |
|
mentioning "a third star 12m from B, 4arcsec; also a fourth." Burnham |
|
|
also says "The other stars referred to are 12.5m, 268.2deg: |
|
|
15.9arcsec; and 12.0m, 145.4deg: 30.9arcsec." These appear to match |
|
|
the BC, AC, and AE pairs in the HJ 1718 mutiple system. We therefore |
|
|
conclude that HJ 1719AB and HJ 1718AB are the same pair. |
