The pressure at higher densities are below the predictions of equations of state that account only for nucleonic degrees of freedom, and thus present a challenge to the microscopic theory of neutron star matter.", "revisions": [ { "version": "v2", "updated": "2010-12-01T17:10:46.000Z" } ], "analyses": { "subjects": [ "21.65.-f", "97.60.Jd", "26.60.Kp" ], "keywords": [ "neutron star matter", "nuclear saturation density", "first astrophysical measurement", "cold matter", "higher densities" ], "tags": [ "journal article" ], "publication": { "publisher": "APS", "journal": "Physical Review D", "year": 2010, "month": "Nov", "volume": 82, "number": 10, "pages": 101301 }, "note": { "typesetting": "TeX", "pages": 0, "language": "en", "license": "arXiv", "status": "editable", "inspire": 846014, "adsabs": "2010PhRvD..82j1301O" } } }
