However, studies of detailed star formation processes in such environments have been limited due to large distances and the challenge of characterizing low-mass sources. Here, I review recent progress and present observational efforts targeting the outer Galaxy and Magellanic Clouds\u2014the nearest regions with metallicities as low as 0.2\u20130.5 Z\u2609. We conducted a multi-wavelength campaign targeting the outer Galaxy source Sh2-284, one of the lowest metallicity star-forming regions in the Milky Way. The synergy of multi-wavelength facilities, including ALMA and JWST, enables simultaneous characterization of dense gas and newly formed stellar populations. I will also present a sample study of massive young stellar objects (YSOs) in the Magellanic Clouds, followed by ALMA long-baseline observations that achieve unprecedented resolution at millimeter wavelengths (~1500 au) to probe fragmentation and kinematics. These results advance our understanding of star formation physics in conditions analogous to the early universe.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Star Formation in Sub-Solar Metallicity Environments: Insights from the outer Galaxy and the Magellanic Clouds &hellip; <a href=\"https:\/\/sci.nao.ac.jp\/seminars\/colloquium\/2025\/02\/26\/2025-03-05\/\" class=\"more-link\"><span class=\"screen-reader-text\">&#8220;2025-03-05&#8221; \u306e<\/span>\u7d9a\u304d\u3092\u8aad\u3080<\/a><\/p>\n","protected":false},"author":30,"featured_media":0,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[1],"tags":[],"class_list":["post-2448","post","type-post","status-publish","format-standard","hentry","category-1"],"_links":{"self":[{"href":"https:\/\/sci.nao.ac.jp\/seminars\/colloquium\/wp-json\/wp\/v2\/posts\/2448","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/sci.nao.ac.jp\/seminars\/colloquium\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/sci.nao.ac.jp\/seminars\/colloquium\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/sci.nao.ac.jp\/seminars\/colloquium\/wp-json\/wp\/v2\/users\/30"}],"replies":[{"embeddable":true,"href":"https:\/\/sci.nao.ac.jp\/seminars\/colloquium\/wp-json\/wp\/v2\/comments?post=2448"}],"version-history":[{"count":1,"href":"https:\/\/sci.nao.ac.jp\/seminars\/colloquium\/wp-json\/wp\/v2\/posts\/2448\/revisions"}],"predecessor-version":[{"id":2449,"href":"https:\/\/sci.nao.ac.jp\/seminars\/colloquium\/wp-json\/wp\/v2\/posts\/2448\/revisions\/2449"}],"wp:attachment":[{"href":"https:\/\/sci.nao.ac.jp\/seminars\/colloquium\/wp-json\/wp\/v2\/media?parent=2448"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/sci.nao.ac.jp\/seminars\/colloquium\/wp-json\/wp\/v2\/categories?post=2448"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/sci.nao.ac.jp\/seminars\/colloquium\/wp-json\/wp\/v2\/tags?post=2448"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
