The main attention is paid to the chemical composition and genetics of stars in the corona of the core (halo) of the Galaxy with highly elliptical orbits and stars with hyperbolic orbits from the vicinity of the Sun. The possible role of various mechanisms of acceleration of the spatial motion of stars in the formation of the stellar corona (halo) of the Galaxy and stars with high hyperbolic (<italic>v </italic>&gt; 500 km/s) velocities in the vicinity of the Sun is considered. Supernova explosions in close binaries and the disintegration of unstable close triple stars have been proposed as possible mechanisms for the acceleration of these stars. The abundance of iron in corona stars coincides with the abundance of iron in globular clusters, which is an argument in favor of their relationship. It is shown that about 7% of low metallicity stars ([Fe/H] &lt; 3), judging by the position of their apexes, may belong to the “first” stars of the Galaxy, or they are products of the decay of low-mass satellites of the Galaxy.</p></abstract><trans-abstract xml:lang="ru"><p>Продолжено исследование кинематики и генетики звездных популяций Галактики в пределах сферы радиусом 300 парсек на основе каталога Gaia (AG300). Основное внимание уделено химическому составу и генетике звезд короны ядра (гало) Галактики с высокоэллиптическими орбитами и звезд с гиперболическими орбитами из окрестностей Солнца. Рассмотрена возможная роль различных механизмов ускорения пространственного движения звезд в формировании звездной короны (гало) Галактики и звезд с высокими гиперболическими (<italic>ν </italic>&gt; 500 км/с) скоростями в окрестностях Солнца. Взрывы сверхновых звезд в тесных двойных и распад неустойчивых тесных тройных звезд предложен в качестве возможных механизмов ускорения этих звезд. Обилие железа в звездах короны совпадает с обилием железа в шаровых скоплениях, что является аргументом в пользу их родства. Показано, что около 7% звезд низкой металличности ([Fe/H] &lt; 3), судя по положению их апексов, могут принадлежать «первым» звездам Галактики, либо они продукт распада спутников Галактики малой массы.</p></trans-abstract><kwd-group xml:lang="en"><kwd>stellar streams</kwd><kwd>astrometry</kwd><kwd>solar neighborhood</kwd><kwd>Gaia DR3 catalog</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>звездные потоки</kwd><kwd>астрометрия</kwd><kwd>окрестности Солнца</kwd><kwd>каталог Gaia DR3</kwd></kwd-group><funding-group/></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>А.
