These stars are relatively young (between 100 and 600Myr) and chromospherically active (X-ray sources), although they rotate slowly. I determine the spectroscopic orbits of the inner subsystems (periods 19.4, 14.1, 5.6, 20.3days) and the orbits of the outer systems (periods 1.75, 51, 27, 500years, respectively). For HIP 7601 and 13498, the combined spectro-interferometric outer orbits produce direct measurement of the masses of all of the components, allowing for a comparison with stellar models. The 6708{AA} lithium line is present and its strength is measured in each component individually by subtracting the contributions of the other components. The inner and outer orbits of HIP 7601 are nearly circular, likely co-planar, and have a modest period ratio of 1:33. This study contributes to the characterization of hierarchical multiplicity in the solar neighborhood and provides data for testing stellar evolutionary models and chronology.2016AJ....152...11Thttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/AJ/152/11CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toB/sb9 : 9th Catalogue of Spectroscopic Binary Orbits (Pourbaix+ 2004-2014)B/wds : The Washington Visual Double Star Catalog (Mason+ 2001-2014)V/130 : Geneva-Copenhagen Survey of Solar neighbourhood III (Holmberg+, 2009)I/311 : Hipparcos, the New Reduction (van Leeuwen, 2007)I/239 : The Hipparcos and Tycho Catalogues (ESA 1997)III/135 : Henry Draper Catalogue and Extension (Cannon+ 1918-1924; ADC 1989)J/AJ/150/50 : Speckle interferometry at SOAR in 2014 (Tokovinin+, 2015)J/AJ/149/195 : Spectroscopy of the quadruple system HD91962 (Tokovinin+, 2015)J/AJ/149/8 : RV of southern visual multiple stars (Tokovinin+, 2015)J/AJ/147/87 : From binaries to multiples.
