The non-minimal interaction between fluid variables and the Ricci scalar generates a vacuum-like equation of state in the interior, while the exterior remains exactly Schwarzschild. The two spacetimes are glued through a thin shell at the junction. The interior metric is non-singular…","published":"2026-09-29T04:00:00Z","seen":"2026-09-29T07:46:41Z","lang":"en","source":{"id":"arxiv-astro-ph","name":"arXiv astro-ph (astrophysics)","domain":"arxiv.org","outlet":{"wikidata":"Q118398","name":"arXiv","type":"website","country":"US","designations":["bibliographic database","disciplinary repository","online database","open science tool","preprint server","website"]}},"via":"arxiv-astro-ph","topics":["space","astrophysics","gr-qc","astro-ph.he","hep-ph"],"authors":["Debanjan Debnath, Rikpratik Sengupta, Kaushik Bhattacharya"],"entities":[{"id":"Q589","name":"black hole","type":"event"}],"story":"st_5r4wvhwwqj76vtr6mesq","category":"science-technology","category_p":0.8999999761581421,"sentiment":"neutral","tone":0.009999999776482582,"political":0.03999999910593033}]}
