Recent investigations by the College Observatory have led to a definite advance in knowledge of the star H. D. 161114 (xxOphinchi), according to Circular 292 issued by the Observatory last night.
The star was first noted in 1908 by Mrs. Fleming. In 1924, Beljawsky suggested a periodicity of ten and one half months. The name "iron star" has been suggested, because the enhanced spectrum of iron is present in emission with greater purity than in any ordinary laboratory source.
The Observatory research has also revealed the fact that the light variations are of a most unusual nature, recalling those of the variables of the R. Coronal Borealis type, but the range in brightness is considerably smaller than is usual for such stars.
