We resolved for the first time 59 new pairs or subsystems in known binaries, mostly among nearby dwarf stars. This work continues our long-term speckle program. Its main goal is to monitor orbital motion of close binaries, including members of high-order hierarchies and Hipparcos pairs in the solar neighborhood. We also report observations of 892 members of young moving groups and associations, where we resolved 103 new pairs. 2021AJ....162...41T https://cdsarc.cds.unistra.fr/viz-bin/cat/J/AJ/162/41 Catalog Research IsServedBy TAP VizieR generic service IsServedBy Conesearch service related-to B/wds : The Washington Visual Double Star Catalog (Mason+ 2001-2020) I/345 : Gaia DR2 (Gaia Collaboration, 2018) IV/38 : TESS Input Catalog - v8.0 (TIC-8) (Stassun+, 2019) J/AJ/139/743 : Speckle interferometry in 2008-09 (Tokovinin+, 2010) J/AJ/143/42 : Speckle interferometry with SOAR 2010 & 2011 (Hartkopf+, 2012) J/AJ/144/56 : Speckle interferometry at SOAR in 2012 (Tokovinin+, 2012) J/AJ/147/123 : Speckle interferometry with SOAR in 2012-2013 (Tokovinin+, 2014) J/AJ/150/50 : Speckle interferometry at SOAR in 2014 (Tokovinin+, 2015) J/AJ/150/151 : DSSI observations binaries.
