| CHR 100 |
eps Cyg = 53 Cyg = Aljanah. A spectroscopic binary. |
|
|
van Maanan notes a common high-proper motion companion located 1'.3 |
Maa1934 |
|
west and 0'.1 south of eps Cyg. The companion (photographic magnitude |
|
|
~14.8) was found on two plates taken with the Mt. Wilson 60inch over |
|
|
an interval of 12 years. |
|
|
1991.8987: This finally confirms the discovery observation of this |
|
|
component, made in 1983 (McAlister et al 1987). A number of unresolved |
McA1987b |
|
observations of this very close system, dating from 1979 to 1981, were |
|
|
published by Hartkopf & McAlister (1984). |

|
A single lined spectroscopic binary with a period of 55 yr yields an |
Grf1994 |
|
estimated semi-major axis of 1.05", so the companion has only escaped |
|
|
visual resolution only due to its faintness. MK III measures of the |
MkT2003 |
|
diameter and no loss of coherence rules out companions with dm < 5.7. |
|
|
It is possible that CHR 100 is an artifact caused by wave-front |
Tok2010b |
|
distortions in the dome. The star was likely observed near the zenith |
|
|
and the separation of the putative companion is close to the first |
|
|
diffraction ring, as typical for such artifacts. |

Mk III Limb-darkened diameter 4.62 mas. |

Mk III Limb-darkened diameter 4.612 +/- 0.046 mas. |
