Stars carry \nsignatures of the conditions in their birth environment and of their \nsubsequent history, meaning we can use the stars as\n fossil records to reconstruct the evolution of the Milky Way. We can \nalso use the constraints on in-situ formation of external galaxies, \nwhere individual stars cannot be resolved and this kind of study is \nimpossible.\n<br>\n\nOne challenge is to achieve the necessary accuracy in stellar \nparameters for a representative number of stars. Determining physical \nproperties of stars such as mass, radius, and especially age is \nremarkably difficult using traditional techniques. In the\n last few decades, the study of stellar pulsations or asteroseismology \nhas led to a dramatic development in the precise measure of stellar \nparameters.\nStellar pulsations are directly related to the internal properties \nof stars and thus to the nuclear processes in the stellar interior, \nbased on which relatively precise stellar ages can be determined.\n<br>\n\nI have compiled the largest ensemble of red giant stars to date with \nmeasured elemental abundances, astrometric quantities, and precise ages \nfrom asteroseismology. The aim of my project is to build a chronology of\n the Milky Way galaxy and study the age aspect\n of the chemical and kinematic features of the Galactic disk. Using a \ndata-driven clustering algorithm, I am looking at the similarities and \ndifferences between stars born at different epochs, studying the \nsignatures of events in the Milky Way&#8217;s past.<br><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Chronology of the Galactic disk with Asteroseismology Amalie Stokholm (SAC, Aarhus University) The Milky Way galaxy has been shaped by<\/p>\n<p class=\"readmore\"><a href=\"https:\/\/sites.lesia.obspm.fr\/the-good-vibrations-seminars\/events\/good-vibrations-seminar-6-amalie-stockholm-sac-aarhus-university\/\" title=\"Read Good Vibrations Seminar #6: Amalie Stokholm (SAC, Aarhus University, Denmark)\">Read more &raquo;<\/a><\/p>\n","protected":false},"author":73,"featured_media":396,"comment_status":"open","ping_status":"closed","template":"","categories":[],"class_list":["post-332","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\/332","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=332"}],"version-history":[{"count":6,"href":"https:\/\/sites.lesia.obspm.fr\/the-good-vibrations-seminars\/wp-json\/wp\/v2\/eap_event\/332\/revisions"}],"predecessor-version":[{"id":623,"href":"https:\/\/sites.lesia.obspm.fr\/the-good-vibrations-seminars\/wp-json\/wp\/v2\/eap_event\/332\/revisions\/623"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/sites.lesia.obspm.fr\/the-good-vibrations-seminars\/wp-json\/wp\/v2\/media\/396"}],"wp:attachment":[{"href":"https:\/\/sites.lesia.obspm.fr\/the-good-vibrations-seminars\/wp-json\/wp\/v2\/media?parent=332"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/sites.lesia.obspm.fr\/the-good-vibrations-seminars\/wp-json\/wp\/v2\/categories?post=332"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
