The results show that low-order radial modes can be self-excited. Their excitation is the result of radiation and the coupling between convection and oscillations. Turbulent pressure has important effects on the excitation of oscillations in red variables.", "revisions": [ { "version": "v1", "updated": "2018-08-29T03:28:15.000Z" } ], "analyses": { "keywords": [ "red giants", "turbulent convection", "pulsation stability", "low-order radial modes", "anisotropic time-dependent theory" ], "tags": [ "journal article" ], "note": { "typesetting": "TeX", "pages": 7, "language": "en", "license": "arXiv", "status": "editable" } } }
