cds-question@unistra.frmultiple-starsinterferometryResults of speckle observations at the 4.1m SOAR telescope in 2012 (158 measures of 121 systems, 27 non-resolutions) are reported. The aim is to follow fast orbital motion of recently discovered or neglected close binaries and sub-systems. Here, eight previously known orbits are defined better, two more are completely revised, and five orbits are computed for the first time. Using differential photometry from Hipparcos or speckle and the standard relation between mass and absolute magnitude, the component's masses and dynamical parallaxes are estimated for all 15 systems with new or updated orbits. Two astrometric binaries HIP 54214 and 56245 are resolved here for the first time, another eight are measured. We highlight several unresolved pairs that may actually be single despite multiple historic measures, such as 104 Tau and f Pup AB. Continued monitoring is needed to understand those enigmatic cases.2012AJ....144...56Thttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/AJ/144/56CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toB/wds : The Washington Visual Double Star Catalog (Mason+ 2001-2013)I/239 : The Hipparcos and Tycho Catalogues (ESA 1997)V/39 : 4th Catalog of Orbits of Visual Binaries (Worley+, 1983)J/AJ/144/7 : NIR imaging of HIP astrometric binaries (Tokovinin+, 2012)J/AJ/143/42 : SOAR speckle interferometry in 2010 & 2011 (Hartkopf+, 2012)J/AJ/139/743 : Speckle interferometry in 2008-09 (Tokovinin+, 2010)J/A+A/464/377 : HIP binaries with radial velocities (Frankowski+, 2007)J/AJ/133/1209 : 14 visual double stars orbits & system masses (Docobo+, 2007)J/AJ/129/2420 : Proper motion derivatives of binaries (Makarov+, 2005)J/A+A/442/365 : Astrometric orbits of SB9 stars (Jancart+, 2005)J/AJ/127/1727 : Differential magnitudes of binary stars (Horch+, 2004)J/AJ/123/1023 : Binary star orbits (Seymour+, 2002)J/AJ/121/3224 : Speckle interferometry of HIP binaries (Mason+, 2001)J/A+A/367/865 : Speckle observations of binary systems (Prieur+ 2001)J/AJ/119/3084 : ICCD speckle obs. of binary stars.
