The designation
WDS J04070-1000B
corresponds to the secondary of the close double
HDS 521
=
HIP 19206
, which is about 8.7° away. This "system" (actually
WDS J04070-1000AB,C
) was introduced by
Shaya & Olling (2011)
who assign a probability of 95% that this pair
HIP 19206
+
HIP 21489
=
Shy 165
has been bound − but it seems difficult to call this association a
double star
... And it seems that the
reference to this paper
is missing among the references for that star; in fact it looks like most of the stars quoted in that paper miss this reference!
