The structure profiles and properties of neutron stars such as mass, radius and compactness are obtained through numerical methods using quadratic, exponential, and logarithmic f(Q) models. The results indicate that nonmetricity affects the interior profile deviations of the star, which in turn influence the properties of stars, as illustrated in the mass-radius relation diagram. This effect allows the star to accommodate either more or less matter compared to GR, resulting in a different total mass. For the quadratic model, we cannot generate larger masses, whereas the other two models can give consistent results for both smaller and larger masses of the observed stars. By tuning model parameters, we obtain Script M-Script R diagrams that are compatible with observational constraints from NICER and LIGO.","subitem_description_language":"en","subitem_description_type":"Abstract"},{"subitem_description":"SAN acknowledges the financial support provided by Hiroshima University, Japan through Japan Student Services Organization (JASSO) Fellowship to carry out the research work.","subitem_description_language":"en","subitem_description_type":"Other"}]},"item_1617186643794":{"attribute_name":"Publisher","attribute_value_mlt":[{"subitem_publisher":"IOP Science","subitem_publisher_language":"en"}]},"item_1617186660861":{"attribute_name":"Date","attribute_value_mlt":[{"subitem_date_issued_datetime":"2025-09-03","subitem_date_issued_type":"Available"}]},"item_1617186702042":{"attribute_name":"Language","attribute_value_mlt":[{"subitem_language":"eng"}]},"item_1617186920753":{"attribute_name":"Source Identifier","attribute_value_mlt":[{"subitem_source_identifier":"1475-7516","subitem_source_identifier_type":"ISSN"}]},"item_1617187056579":{"attribute_name":"Bibliographic Information","attribute_value_mlt":[{"bibliographicIssueDates":{"bibliographicIssueDate":"2024-09-03","bibliographicIssueDateType":"Issued"},"bibliographicPageStart":"none","bibliographic_titles":[{"bibliographic_title":"JOURNAL OF COSMOLOGY AND ASTROPARTICLE PHYSICS","bibliographic_titleLang":"en"}]}]},"item_1617258105262":{"attribute_name":"Resource Type","attribute_value_mlt":[{"resourcetype":"journal article","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_1617265215918":{"attribute_name":"Version Type","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_ab4af688f83e57aa","subitem_version_type":"AM"}]},"item_1617353299429":{"attribute_name":"Relation","attribute_value_mlt":[{"subitem_relation_type":"isVersionOf","subitem_relation_type_id":{"subitem_relation_type_id_text":"10.1088/1475-7516/2024/09/011","subitem_relation_type_select":"DOI"}}]},"item_1617605131499":{"attribute_name":"File","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2025-09-03"}],"fileDate":[{"fileDateType":"Available","fileDateValue":"2025-09-03"}],"filename":"JCAP_2024.pdf","filesize":[{"value":"6.2 MB"}],"format":"application/pdf","mimetype":"application/pdf","url":{"objectType":"fulltext","url":"https://hiroshima.repo.nii.ac.jp/record/2040697/files/JCAP_2024.pdf"},"version_id":"50774127-5385-4945-b0e7-a98ed2c912b2"},{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2025-09-03"}],"fileDate":[{"fileDateType":"Available","fileDateValue":"2025-09-03"}],"filename":"arXiv-2407.03669v2.zip","filesize":[{"value":"6.7 MB"}],"format":"application/zip","mimetype":"application/zip","url":{"objectType":"dataset","url":"https://hiroshima.repo.nii.ac.jp/record/2040697/files/arXiv-2407.03669v2.zip"},"version_id":"5b9f6577-9d13-482d-9a81-549c411e63d3"}]},"item_1732772494514":{"attribute_name":"備考","attribute_value_mlt":[{"subitem_text_language":"en","subitem_text_value":"he full-text file will be made open to the public on [ 3 Sep 2025］ in accordance with publisher's 'Terms and Conditions for Self-Archiving'"}]},"item_title":"Neutron star in covariant f(Q) gravity","item_type_id":"40036","owner":"83","path":["1730444907710"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2025-06-06"},"publish_date":"2025-06-06","publish_status":"0","recid":"2040697","relation_version_is_last":true,"title":["Neutron star in covariant f(Q) gravity"],"weko_creator_id":"83","weko_shared_id":-1},"updated":"2025-07-07T05:15:18.990652+00:00"}
