Hence, usually, the stars formed will be homogeneous in their chemical composition of elemental abundances.<\/li><li>But, there are clusters which deviate from this norm. One is being Omega Centauri, the brightest and the largest globular cluster in our Galaxy, the Milky Way.<\/li><li>The different stars of Omega Centauri do not show the same metal content, a parameter that indicates its age, but a large range in it.Though there are estimations of He-enhancement in the H-core burning main-sequence stars (like Sun) of Omega Cen, this is the first-ever spectroscopic determination of He-abundance in Omega Centauri.<\/li><\/ul>\n\n\n\n<p class=\"has-text-align-right wp-block-paragraph\"><strong>By: Arpit Mishra<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Link:<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><a href=\"https:\/\/dst.gov.in\/iia-scientists-discover-he-enhanced-cool-bright-stars-among-metal-rich-parts-omega-centauri-globular\">https:\/\/dst.gov.in\/iia-scientists-discover-he-enhanced-cool-bright-stars-among-metal-rich-parts-omega-centauri-globular<\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Question:What is Omega Centauri?(a) Sun like star(b) Galaxy like Milky Way(c) Globular cluster in Milky Way(d) None of theseAnswer:(c) Context: A team of scientists from the Indian Institute of Astrophysics (IIA), an autonomous institute under the Department of Science &amp; Technology (DST), has discovered He-enhanced cool bright stars among the metal-rich parts of Omega Centauri [&hellip;]<\/p>\n","protected":false},"author":2,"featured_media":100279,"comment_status":"open","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[1131],"tags":[7422],"class_list":["post-100278","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-dssn","tag-current-affairs-science-news___en"],"_links":{"self":[{"href":"https:\/\/www.edristi.in\/hi\/%e0%a4%b9%e0%a5%8b%e0%a4%ae\/wp-json\/wp\/v2\/posts\/100278","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.edristi.in\/hi\/%e0%a4%b9%e0%a5%8b%e0%a4%ae\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.edristi.in\/hi\/%e0%a4%b9%e0%a5%8b%e0%a4%ae\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.edristi.in\/hi\/%e0%a4%b9%e0%a5%8b%e0%a4%ae\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/www.edristi.in\/hi\/%e0%a4%b9%e0%a5%8b%e0%a4%ae\/wp-json\/wp\/v2\/comments?post=100278"}],"version-history":[{"count":1,"href":"https:\/\/www.edristi.in\/hi\/%e0%a4%b9%e0%a5%8b%e0%a4%ae\/wp-json\/wp\/v2\/posts\/100278\/revisions"}],"predecessor-version":[{"id":100280,"href":"https:\/\/www.edristi.in\/hi\/%e0%a4%b9%e0%a5%8b%e0%a4%ae\/wp-json\/wp\/v2\/posts\/100278\/revisions\/100280"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.edristi.in\/hi\/%e0%a4%b9%e0%a5%8b%e0%a4%ae\/wp-json\/wp\/v2\/media\/100279"}],"wp:attachment":[{"href":"https:\/\/www.edristi.in\/hi\/%e0%a4%b9%e0%a5%8b%e0%a4%ae\/wp-json\/wp\/v2\/media?parent=100278"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.edristi.in\/hi\/%e0%a4%b9%e0%a5%8b%e0%a4%ae\/wp-json\/wp\/v2\/categories?post=100278"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.edristi.in\/hi\/%e0%a4%b9%e0%a5%8b%e0%a4%ae\/wp-json\/wp\/v2\/tags?post=100278"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
