The interpretation, however, depends sensitively on the tracer selection, the tracer density profile, gradient terms in the Jeans equation, and non-axisymmetric perturbations in the outer disk. We present a more self-consistent Jeans analysis of the MW RC and reassess whether the outer decline remains after a revised treatment…","published":"2026-09-28T04:00:00Z","seen":"2026-09-28T07:43:12Z","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","astro-ph.ga"],"authors":["Yongjun Jiao, Francois Hammer, Istiak Akib, Yanbin Yang, Haifeng Wang"],"entities":[{"id":"Q1752705","name":"Milky Way","type":"place"}],"story":"st_2ryuffgs4gozfk7lkuda","category":"science-technology","category_p":0.5899999737739563,"sentiment":"neutral","tone":0.05999999865889549,"political":0.029999999329447746}]}
