They show transient phenomena called outbursts. The most plausible model for outbursts is thermal-viscous instability triggered by partial ionization of hydrogen in the accretion disk. However, recent development of time-domain astronomy has found various kinds of outbursts that cannot be explained by the standard disk instability model. I have focused on multi-wavelength observations and numerical simulations to establish a grand unified model for rich variety of outbursts. In this presentation, I introduce an example for interpreting a weired light curve in a well-known white-dwarf binary by both the above two approaches. I present our recent work for improving the numerical code by implementing variable inner disk radius. Additionally, I will discuss our ongoing study and future plans on 2D numerical simulations and timing spectroscopy of fast variability.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Multi-wavelength observations and numerical simulations of compact binary transients Speaker:\u00a0Mariko Kimura (K &hellip; <a href=\"https:\/\/sci.nao.ac.jp\/seminars\/colloquium\/2026-6-3\/\" class=\"more-link\"><span class=\"screen-reader-text\">&#8220;2026-6-3&#8221; \u306e<\/span>\u7d9a\u304d\u3092\u8aad\u3080<\/a><\/p>\n","protected":false},"author":32,"featured_media":0,"parent":0,"menu_order":0,"comment_status":"closed","ping_status":"closed","template":"","meta":{"footnotes":""},"class_list":["post-2686","page","type-page","status-publish","hentry"],"_links":{"self":[{"href":"https:\/\/sci.nao.ac.jp\/seminars\/colloquium\/wp-json\/wp\/v2\/pages\/2686","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/sci.nao.ac.jp\/seminars\/colloquium\/wp-json\/wp\/v2\/pages"}],"about":[{"href":"https:\/\/sci.nao.ac.jp\/seminars\/colloquium\/wp-json\/wp\/v2\/types\/page"}],"author":[{"embeddable":true,"href":"https:\/\/sci.nao.ac.jp\/seminars\/colloquium\/wp-json\/wp\/v2\/users\/32"}],"replies":[{"embeddable":true,"href":"https:\/\/sci.nao.ac.jp\/seminars\/colloquium\/wp-json\/wp\/v2\/comments?post=2686"}],"version-history":[{"count":2,"href":"https:\/\/sci.nao.ac.jp\/seminars\/colloquium\/wp-json\/wp\/v2\/pages\/2686\/revisions"}],"predecessor-version":[{"id":2689,"href":"https:\/\/sci.nao.ac.jp\/seminars\/colloquium\/wp-json\/wp\/v2\/pages\/2686\/revisions\/2689"}],"wp:attachment":[{"href":"https:\/\/sci.nao.ac.jp\/seminars\/colloquium\/wp-json\/wp\/v2\/media?parent=2686"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
