We refine the concept of a UV radiation HZ (UV-HZ) by incorporating a temperature-dependent model for RNA precursor synthesis.<\/p>\n<p>Furthermore, we explore a parameterized spectral energy distribution model and adopt an empirical flare frequency distribution for flares on different stars to quantify their UV contribution.<\/p>\n<p>Applying this framework to different flaring stars, we find that the UV-HZ around low-mass stars can extend to inner regions and overlap with the traditional HZ in wide ranges.<\/p>\n<p>Applying the analysis to 9 planets around Kepler flaring stars, three planets are located within both the refined UV-HZ and the LW-HZ without causing ozone depletion. Our findings highlight the significant role of flares in expanding the potential for life around low-mass stars, offering a revised perspective on exoplanet habitability criteria.<\/p>\n<p>Astrobiology,<\/p>\n","protected":false},"excerpt":{"rendered":"Graphical Abstract \u2014 Cell The traditional definition of the circumstellar habitable zone (HZ) focuses on liquid water, but&hellip;\n","protected":false},"author":2,"featured_media":409372,"comment_status":"","ping_status":"","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[7],"tags":[3033,210570,210571,57302,20697,111,139,69,65008,186450,5388,147,210572,107473],"class_list":["post-409371","post","type-post","status-publish","format-standard","has-post-thumbnail","category-science","tag-cell","tag-circumstellar-habitable-zone","tag-flaring-star","tag-habitability","tag-habitable-zone","tag-new-zealand","tag-newzealand","tag-nz","tag-photochemistry","tag-prebiotic-chemistry","tag-rna","tag-science","tag-space-weathe","tag-uv-radiation"],"_links":{"self":[{"href":"https:\/\/www.newsbeep.com\/nz\/wp-json\/wp\/v2\/posts\/409371","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.newsbeep.com\/nz\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.newsbeep.com\/nz\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/nz\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/nz\/wp-json\/wp\/v2\/comments?post=409371"}],"version-history":[{"count":0,"href":"https:\/\/www.newsbeep.com\/nz\/wp-json\/wp\/v2\/posts\/409371\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/nz\/wp-json\/wp\/v2\/media\/409372"}],"wp:attachment":[{"href":"https:\/\/www.newsbeep.com\/nz\/wp-json\/wp\/v2\/media?parent=409371"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.newsbeep.com\/nz\/wp-json\/wp\/v2\/categories?post=409371"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.newsbeep.com\/nz\/wp-json\/wp\/v2\/tags?post=409371"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
