Our results show the expected vertical propagation for waves with periods of 3 minutes. Waves with 5-minute periods, i.e., above the acoustic cut-off period, are found to propagate only at the periphery of the plage, and only in the direction in which the field can be reasonably expected to expand. We conclude that field inclination is critically important in the leakage of p-mode oscillations from the photosphere into the chromosphere.", "revisions": [ { "version": "v1", "updated": "2009-08-10T20:00:03.000Z" } ], "analyses": { "keywords": [ "solar chromosphere", "propagation", "employ tomographic observations", "fourier phase-difference analysis", "acoustic cut-off period" ], "tags": [ "journal article" ], "publication": { "doi": "10.1088/0004-637X/702/2/L168", "journal": "The Astrophysical Journal", "year": 2009, "month": "Sep", "volume": 702, "number": 2 }, "note": { "typesetting": "TeX", "pages": 4, "language": "en", "license": "arXiv", "status": "editable", "inspire": 828228, "adsabs": "2009ApJ...702L.168D" } } }
