| 内容記述 | We have obtained new, high angular resolution far-infrared (FIR) maps (at 50 and 100 microns) of the star forming region Cepheus A and polarimetric images (1.65 and 2.2 microns) of the reflection nebulosity, IRS6, associated with this young stellar object. Our results are consistent with current star formation theories: a young stellar object surrounded by an infalling envelope with a characteristic density distribution of n(sub d)(r) proportional to r(exp -1.5), a circumstellar disk, and a cavity (R(sub i) approx. 0.07 pc) in which n(sub d) is constant, created by the dispersal of the initial dust cloud by a strong stellar wind. |
