| 英文摘要 | This paper reports the first extremely near infrared observation of two prominence events on Jan. 8, 1999 and Feb. 9, 1999 at H Pfund beta (46525Angstrom) and H Bracket alpha (40512Angstrom) using the McMath Telescope. We scanned the spectrograph slit across the prominences parallel to the limb to obtain three-dimensional data cubes (two spatial dimensions and one spectral dimension). By fitting these observed lines, we can directly determine some important physical parameters such as Doppler width (Deltalambda(D)), the optical thickness at line center (taulambda(0)), and the line displacement (Deltalambda(0)). Combined with simultaneous observation of Balmer H-alpha, H-beta, and Ca K lines, the new results of structure and dynamics of limb prominence is presented. These results imply that these infrared lines can penetrate through the prominence and become a potential probe and tool, while H-alpha, and H-beta sense the prominence skin only. |
