CHR 57 |
39 Her. A short-period (2.3d) double-lined spectroscopic binary. |
|
|
Hence a triple. |
|
|
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. |
