In addition to being a crucial observational probe of the stellar internal structure, mixed gravity-pressure modes may also provide an efficient mechanism for extracting AM from red-giant cores via wave-driven heat transport.<br><br>In this seminar, I will discuss the role of mixed modes in the AM transport of low-mass red giants. First, I will focus on modelling mixed-mode amplitudes throughout stellar evolution, accounting for radiative damping across different angular degrees. Next, I will present the impact of mixed modes on rotation rates along the red giant branch and in the red clump. These results point to aspects that remain to be understood within this theoretical framework. Finally, I will show the resulting rotation profiles obtained by combining the mixed-mode mechanism with other transport processes, such as meridional circulation and magnetic fields.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\" \/>\n","protected":false},"excerpt":{"rendered":"<p>Modelling angular momentum transport by mixed modes across stellar evolution Beatriz Bordad\u00e1gua (HITS) Current stellar models that include hydrodynamic processes<\/p>\n<p class=\"readmore\"><a href=\"https:\/\/sites.lesia.obspm.fr\/the-good-vibrations-seminars\/events\/good-vibrations-seminar-s04e09-beatriz-bordadagua-heidelberg-institute-for-theoretical-studies-germany\/\" title=\"Read Good Vibrations Seminar S04E09: Beatriz Bordad\u00e1gua (Heidelberg Institute for Theoretical Studies, Germany)\">Read more &raquo;<\/a><\/p>\n","protected":false},"author":104,"featured_media":971,"comment_status":"open","ping_status":"closed","template":"","categories":[],"class_list":["post-938","eap_event","type-eap_event","status-publish","has-post-thumbnail","hentry"],"_links":{"self":[{"href":"https:\/\/sites.lesia.obspm.fr\/the-good-vibrations-seminars\/wp-json\/wp\/v2\/eap_event\/938","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/sites.lesia.obspm.fr\/the-good-vibrations-seminars\/wp-json\/wp\/v2\/eap_event"}],"about":[{"href":"https:\/\/sites.lesia.obspm.fr\/the-good-vibrations-seminars\/wp-json\/wp\/v2\/types\/eap_event"}],"author":[{"embeddable":true,"href":"https:\/\/sites.lesia.obspm.fr\/the-good-vibrations-seminars\/wp-json\/wp\/v2\/users\/104"}],"replies":[{"embeddable":true,"href":"https:\/\/sites.lesia.obspm.fr\/the-good-vibrations-seminars\/wp-json\/wp\/v2\/comments?post=938"}],"version-history":[{"count":2,"href":"https:\/\/sites.lesia.obspm.fr\/the-good-vibrations-seminars\/wp-json\/wp\/v2\/eap_event\/938\/revisions"}],"predecessor-version":[{"id":972,"href":"https:\/\/sites.lesia.obspm.fr\/the-good-vibrations-seminars\/wp-json\/wp\/v2\/eap_event\/938\/revisions\/972"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/sites.lesia.obspm.fr\/the-good-vibrations-seminars\/wp-json\/wp\/v2\/media\/971"}],"wp:attachment":[{"href":"https:\/\/sites.lesia.obspm.fr\/the-good-vibrations-seminars\/wp-json\/wp\/v2\/media?parent=938"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/sites.lesia.obspm.fr\/the-good-vibrations-seminars\/wp-json\/wp\/v2\/categories?post=938"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
