Through the analysis of these hydrogen lines, we identified the presence of Hydrogen in the circumstellar medium (CSM) and progenitor star\u2019s photosphere, the velocity of those components and a possible distribution of the CSM. We proposed a model for the motion of the supernova ejecta and CSM. This work is progressing towards the publication of a paper titled &#8220;A comparative study of type-IIn supernovae, with emphasis on SN2017hcc and SN2023usc&#8221; (Vazhayil et al, submitted). <\/p>\n\n\n\n<h5 class=\"wp-block-heading\">Highlights<\/h5>\n\n\n\n<p>ANID National Doctoral Scholarship<\/p>\n\n\n\n<h5 class=\"wp-block-heading\">Extracurricular activities<\/h5>\n\n\n\n<p>I enjoy traveling, dancing in my own freestyle, and occasionally playing badminton.<\/p>\n\n\n\n<h5 class=\"wp-block-heading\">Contact me<\/h5>\n\n\n\n<p>sethulakshmi.vazhayil [at] mail.udp.cl<\/p>\n\n\n\n<p><a href=\"https:\/\/sethu-websitea.vercel.app\"><strong>Personal website<\/strong><\/a><\/p>\n<\/div>\n<\/div>\n","protected":false},"excerpt":{"rendered":"<p>PhD student, working with Jos\u00e9 Prieto, focusing on the study of core-collapse supernovae, interested in the spectroscopic analysis of Type II supernovae and the velocity structure of the CSM.<\/p>\n","protected":false},"author":4,"featured_media":8564,"menu_order":0,"template":"","meta":{"_monsterinsights_skip_tracking":false,"_monsterinsights_sitenote_active":false,"_monsterinsights_sitenote_note":"","_monsterinsights_sitenote_category":0,"site-sidebar-layout":"default","site-content-layout":"default","ast-global-header-display":"","ast-banner-title-visibility":"","ast-main-header-display":"","ast-hfb-above-header-display":"","ast-hfb-below-header-display":"","ast-hfb-mobile-header-display":"","site-post-title":"disabled","ast-breadcrumbs-content":"","ast-featured-img":"disabled","footer-sml-layout":"","theme-transparent-header-meta":"","adv-header-id-meta":"","stick-header-meta":"","header-above-stick-meta":"","header-main-stick-meta":"","header-below-stick-meta":""},"researcher-category":[256],"acf":[],"_links":{"self":[{"href":"https:\/\/astronomia.udp.cl\/en\/wp-json\/wp\/v2\/researcher\/7318"}],"collection":[{"href":"https:\/\/astronomia.udp.cl\/en\/wp-json\/wp\/v2\/researcher"}],"about":[{"href":"https:\/\/astronomia.udp.cl\/en\/wp-json\/wp\/v2\/types\/researcher"}],"author":[{"embeddable":true,"href":"https:\/\/astronomia.udp.cl\/en\/wp-json\/wp\/v2\/users\/4"}],"version-history":[{"count":7,"href":"https:\/\/astronomia.udp.cl\/en\/wp-json\/wp\/v2\/researcher\/7318\/revisions"}],"predecessor-version":[{"id":8677,"href":"https:\/\/astronomia.udp.cl\/en\/wp-json\/wp\/v2\/researcher\/7318\/revisions\/8677"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/astronomia.udp.cl\/en\/wp-json\/wp\/v2\/media\/8564"}],"wp:attachment":[{"href":"https:\/\/astronomia.udp.cl\/en\/wp-json\/wp\/v2\/media?parent=7318"}],"wp:term":[{"taxonomy":"researcher-category","embeddable":true,"href":"https:\/\/astronomia.udp.cl\/en\/wp-json\/wp\/v2\/researcher-category?post=7318"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
