New kinematic age estimates for the three components of the association were obtained, with the age of UCL and LCC being 17.7 ± 2.4 Myr, and the age of US being 6.4 ± 1.7 Myr. The parameters of the residual velocities US, UCL and LCC were estimated.</p></abstract><trans-abstract xml:lang="ru"><p>Кинематические свойства ассоциации Sco-Cen изучены с использованием пространственных скоростей молодых звезд. Получены новые кинематические оценки возраста трех составляющих ассоциации, при этом возраст UCL и LCC оказался равным 17.7 ± 2.4 млн лет, а возраст US составил 6.4 ± 1.7 млн лет. Даны оценки параметров эллипсоида остаточных скоростей US, UCL и LCC.</p></trans-abstract><kwd-group xml:lang="en"><kwd>kinematics</kwd><kwd>star formation</kwd><kwd>T Tauri stars</kwd><kwd>stellar associations</kwd><kwd>Scorpio-Centauri association</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>кинематика</kwd><kwd>звездообразование</kwd><kwd>звезды типа Т Тельца</kwd><kwd>звездные ассоциации</kwd><kwd>ассоциация Скорпиона-Центавра</kwd></kwd-group><funding-group/></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>A.
