However, computing pulsation frequencies of rotating stars is not a trivial effort. While some types of pulsators can be modelled with first-order approaches (the commonly used Ledoux splittings), this is not the case for many others, requiring higher-order approaches. For massive main-sequence pulsators (i.e. \u03b2 Cep pulsators), the main contributing factor is the deformation of the stellar surface away from a perfect sphere. This introduces shifts in the overal pulsation frequencies, and introduces asymmetries in rotationally split multiplets, which one needs to take into account when modelling these pulsation frequencies.<\/p>\n\n\n\n<p>In this presentation, I will discuss how the recently released oscillation code StORM (https:\/\/stellar-oscillations.org) makes it possible to include these rotational effects. I will also touch upon some of the other aspects of StORM that might make you want to use it (it&#8217;s fast!), and discuss some ongoing applications.<\/p>\n\n\n\n<video src=\"https:\/\/asteroseismolo.gy\/goodvibes\/S4\/1.mp4\" controls style=\"width: 100%\">\nVideo recording can be found <a href=\"https:\/\/asteroseismolo.gy\/goodvibes\/S4\/1.mp4\">here<\/a>.\n<\/video>\n","protected":false},"excerpt":{"rendered":"<p>How to compute pulsation frequencies of rotating stars: a look at the pulsation code StORM Vincent Vanlaer (KU Leuven, Belgium)<\/p>\n<p class=\"readmore\"><a href=\"https:\/\/sites.lesia.obspm.fr\/the-good-vibrations-seminars\/events\/good-vibrations-seminar-s04e01-vincent-vanlaer-ku-leuven-belgium\/\" title=\"Read Good Vibrations Seminar S04E01: Vincent Vanlaer (KU Leuven, Belgium)\">Read more &raquo;<\/a><\/p>\n","protected":false},"author":104,"featured_media":882,"comment_status":"open","ping_status":"closed","template":"","categories":[],"class_list":["post-881","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\/881","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=881"}],"version-history":[{"count":6,"href":"https:\/\/sites.lesia.obspm.fr\/the-good-vibrations-seminars\/wp-json\/wp\/v2\/eap_event\/881\/revisions"}],"predecessor-version":[{"id":906,"href":"https:\/\/sites.lesia.obspm.fr\/the-good-vibrations-seminars\/wp-json\/wp\/v2\/eap_event\/881\/revisions\/906"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/sites.lesia.obspm.fr\/the-good-vibrations-seminars\/wp-json\/wp\/v2\/media\/882"}],"wp:attachment":[{"href":"https:\/\/sites.lesia.obspm.fr\/the-good-vibrations-seminars\/wp-json\/wp\/v2\/media?parent=881"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/sites.lesia.obspm.fr\/the-good-vibrations-seminars\/wp-json\/wp\/v2\/categories?post=881"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
