Delta-mu Binaries 2009-07-14T10:10:00Z 1000 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). .. _FK5: http://www.ari.uni-heidelberg.de/publikationen/vhd/vhd032/vhd032.htm .. _FK5 extension: http://www.ari.uni-heidelberg.de/publikationen/vhd/vhd033/vhd033.htm .. _FK5 supplement: http://www.ari.uni-heidelberg.de/publikationen/vhd/vhd034/vhd034.htm Wielen, R.; Dettbarn, C.; Jahrreiß, H.; Lenhardt, H.; Schwan, H. binary-stars proper-motions astrometric-binary-stars catalogs 1999A&A...346..675W http://www.ari.uni-heidelberg.de/datenbanken/dmubin/ Optical //scs#pgs-pos-index Position ICRS Epoch J2000 "raj2000" "dej2000" For the expressions used to obtain the F-measures, see 1999A&A...346..675W ("Source" in the metadata). mu0F is a proper motion derived from the FK5 and Hipparcos positions, mu0G is a proper motion derived from the GC and Hipparcos positions.
