Solving the Tolman-Oppenheimer-Volkoff equation with a hot quark equation of state, we find stable solutions with a maximum…","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","hep-ph","astro-ph.co","gr-qc"],"authors":["Domenec Espriu"],"entities":[{"id":"Q2473641","name":"Quark","type":"other"},{"id":"Q79925","name":"dark matter","type":"other"}],"story":"st_z24bsrxkbnrcixtft53a","category":"science-technology","category_p":0.8299999833106995,"sentiment":"neutral","tone":0.009999999776482582,"political":0.019999999552965164}]}
