A collection of binary stars with a difference
in instantaneous proper motion as measured by HIPPARCOS and the long-term
proper motion.
A Δμ binary is an object that has a statistcally signifcant difference
between instantaneous proper motion (as measured by HIPPARCOS) and a
longer-term proper motion as indicated by longer-term observations.
The HIPPARCOS proper motion is taken from the
\RSTservicelink{//dc_tables/show/tableinfo/hipparcos.main}{HIPPARCOS catalogue}.
The mean proper motion is usually either taken directly from a ground-based
astrometric catalogue (after having applied appropriate systematic
corrections), or a new mean proper motion (μ0) is calculated from the
ground-based position(s) and the HIPPARCOS position. The following
catalogues have been used for obtaining mean proper motions:
* FK5_ (Veröff. Astron. Rechen-Inst. No. 32)
* `FK5 extension`_
* `FK5 supplement`_
* Boss' General Catalogue, 1937
* Tycho-2 proper motions, 2000
The basic principles of the method are explained in the paper: Wielen, R.,
Dettbarn, C., Jahreiß, H., Lenhardt, H., Schwan, H.: Indications on the
binary nature of individual stars derived from a comparison of their
HIPPARCOS proper motions with ground-based data (see source metadatum).
The stars listed here are those investigated (ca. 90000)
with one (or more) F-measures exceeding 3.44.
We list many newly detected binaries, but also ones already known from
other data, e.g. visual ones. In many cases of already known binaries, the
F values should be considered as qualitative 'flags' for binarity only,
since the proper motions compared may not refer to the same 'reference
point' (e.g., HIPPARCOS refers to component A, while the FK5 to the
center-of-mass).
