CHR 65 |
Aa,Ab: 30 Dra. Hipparcos Acceleration Double Solution. |
|
|
This system, first announced by McAlister and recalled in a later |
McA1984b |
|
McAlister paper after repeated attempts at confirmation, has been |
McA1993 |
|
restored. While perhaps still spurious, the subsequent confirmation or |
|
|
suspected duplicity (by another technique) makes the discovery |
|
|
measurement somewhat more probable. |
