Asteroseismology can provide precise ages of \nstars. Our objective is to combine NASA TESS data along with the ESA \nGAIA photometric data, to search for, to detect and to analyse \noscillations in cluster members. Since stars in a cluster are assumed to\n have the same age and chemical composition, this provides constraints \nfor the interpretation of asteroseismic data. We analysed the \nintermediate-age open cluster NGC 2477, known to suffer from \ndifferential extinction. Using TESS FFI images, we identified several \nlevels of variability of stars in this cluster, including binaries and \nshort- and long-period oscillating stars. We perform an asteroseismic \nanalysis on a small set of uncontaminated oscillating stars. We used \nMESA and GYRE to make stellar models and to calculate the oscillation \nfrequencies. In this talk, I will present how we constrained the \ncluster&#8217;s age by asteroseismic modelling of oscillating stars using the \ngeneral properties of the cluster along with the frequencies from \noscillating stars.<br><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Age constraints for the open cluster NGC 2477 using asteroseismology from TESS FFI Precise ages of stars are important for<\/p>\n<p class=\"readmore\"><a href=\"https:\/\/sites.lesia.obspm.fr\/the-good-vibrations-seminars\/events\/good-vibrations-seminar-s2e12-dinil-bose-palakkatharappil-observatoire-de-la-cote-dazur-nice\/\" title=\"Read \u201cGood Vibrations Seminar S2E12\u201d: Dinil Bose Palakkatharappil (Observatoire de la C\u00f4te d&#8217;Azur, France)\">Read more &raquo;<\/a><\/p>\n","protected":false},"author":73,"featured_media":673,"comment_status":"open","ping_status":"closed","template":"","categories":[],"class_list":["post-634","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\/634","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\/73"}],"replies":[{"embeddable":true,"href":"https:\/\/sites.lesia.obspm.fr\/the-good-vibrations-seminars\/wp-json\/wp\/v2\/comments?post=634"}],"version-history":[{"count":4,"href":"https:\/\/sites.lesia.obspm.fr\/the-good-vibrations-seminars\/wp-json\/wp\/v2\/eap_event\/634\/revisions"}],"predecessor-version":[{"id":789,"href":"https:\/\/sites.lesia.obspm.fr\/the-good-vibrations-seminars\/wp-json\/wp\/v2\/eap_event\/634\/revisions\/789"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/sites.lesia.obspm.fr\/the-good-vibrations-seminars\/wp-json\/wp\/v2\/media\/673"}],"wp:attachment":[{"href":"https:\/\/sites.lesia.obspm.fr\/the-good-vibrations-seminars\/wp-json\/wp\/v2\/media?parent=634"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/sites.lesia.obspm.fr\/the-good-vibrations-seminars\/wp-json\/wp\/v2\/categories?post=634"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
