Although, theoretically in general relativity, a surplus angle is hardly to be obtained in the presence of ordinary matter with positive energy distribution, it seems natural in Horava-Lifshitz gravity. We present the sudden disappearance and reappearance of a star image as an astrophysical effect of a surplus angle. We also consider matter configurations of all possible power law behaviors coupled to Horava-Lifshitz gravity and obtain a series of exact solutions.", "revisions": [ { "version": "v2", "updated": "2009-12-08T05:44:14.000Z" } ], "analyses": { "subjects": [ "04.50.Kd" ], "keywords": [ "horava-lifshitz gravity", "surplus solid angle", "exact solution", "surplus angle", "power law behaviors" ], "tags": [ "journal article" ], "publication": { "publisher": "APS", "journal": "Physical Review D", "year": 2009, "month": "Dec", "volume": 80, "number": 12, "pages": 124002 }, "note": { "typesetting": "TeX", "pages": 23, "language": "en", "license": "arXiv", "status": "editable", "inspire": 826024, "adsabs": "2009PhRvD..80l4002K" } } }
