It is known that in systems with multiple stars, the the inner planets are influenced by the bodies of the outer parts of the system. Gravitational instabilities, the effects of accretion and collisions with planetesimals and  the long-term gravitational disturbances, which typically leads to migration of bodies in multi-planet systems, come into play. <\/p>\n\n\n\n<p>More details can be found <a href=\"https:\/\/www.asu.cas.cz\/articles\/2080\/19\/na-cem-pracujeme-planety-v-hvezdnych-systemech-s-hnedym-trpaslikem\" target=\"_blank\" rel=\"noreferrer noopener\">on the ASU website<\/a>.<\/p>\n\n\n\n<h4 class=\"wp-block-heading\">More information and contact <\/h4>\n\n\n\n<ul class=\"wp-block-list\">\n<li>source: <a rel=\"noreferrer noopener\" href=\"https:\/\/www.asu.cas.cz\/articles\/2080\/19\/na-cem-pracujeme-planety-v-hvezdnych-systemech-s-hnedym-trpaslikem\" target=\"_blank\">Na \u010dem pracujeme: Planety v&nbsp;hv\u011bzdn\u00fdch syst\u00e9mech s&nbsp;hn\u011bd\u00fdm trpasl\u00edkem<\/a>, M. \u0160vanda (in Czech)<\/li>\n\n\n\n<li>J. \u0160ubjak a&nbsp;kol., <em>Search for planets around stars with wide brown dwarfs<\/em>, Astronomy &amp; Astrophysics, in press, preprint <a rel=\"noreferrer noopener\" href=\"https:\/\/arxiv.org\/abs\/2212.03757\" target=\"_blank\">arXiv:2212.03757<\/a><\/li>\n\n\n\n<li>Contact:&nbsp;Mgr.
