Much of the prior work on filament/prominence structure can be divided between studies that use a polychromatic approach with targeted campaign observations, and those that use synoptic observations, frequently in only one or two wavelengths. The superior time resolution, sensitivity and near-synchronicity of data from the Solar Dynamics Observatory's Advanced Imaging Assembly allow us to combine these two techniques using photo-ionisation continuum opacity to determine the spatial distribution of hydrogen in filament material. We apply the combined techniques to SDO/AIA observations of a filament which erupted during the spectacular coronal mass ejection on 2011 June 07. The resulting 'polychromatic opacity imaging' method offers a powerful way to track partially ionised gas as it erupts through the solar atmosphere on a regular basis, without the need for co-ordinated observations, thereby readily offering regular, realistic mass-distribution estimates for models of these erupting structures.", "revisions": [ { "version": "v2", "updated": "2013-02-08T23:12:06.000Z" } ], "analyses": { "keywords": [ "high-cadence euv images", "rapidly-moving prominence material", "mass estimates", "dynamics observatorys advanced imaging", "observatorys advanced imaging assembly" ], "tags": [ "journal article" ], "publication": { "journal": "The Astrophysical Journal", "year": 2013, "month": "Feb", "volume": 764, "number": 2, "pages": 165 }, "note": { "typesetting": "TeX", "pages": 9, "language": "en", "license": "arXiv", "status": "editable", "inspire": 1215045, "adsabs": "2013ApJ...764..165W" } } }
