The model has a negative radial velocity gradient giving rise to equatorward migration of magnetic activity patterns. In addition the model develops longitudinal variability with activity patches travelling in longitude. These patches may be associated with active longitudes.", "revisions": [ { "version": "v1", "updated": "2005-12-29T09:19:04.000Z" } ], "analyses": { "keywords": [ "magnetic helicity", "active longitudes", "two-dimensional mean field dynamo model", "connection", "radial velocity gradient giving rise" ], "note": { "typesetting": "TeX", "pages": 6, "language": "en", "license": "arXiv", "status": "editable", "inspire": 701494, "adsabs": "2005astro.ph.12639B" } } }
