我们提出了两个前主序星 T Tau 和 SU Aur 的星周盘模型。这些模型基于红外和毫米波长的干涉数据以及文献中的红外光度测量。通过基于无源扁平磁盘模型计算参数概率来检查磁盘的物理属性。该模型充分拟合了 SU Aur 的数据，但不适用于 T Tau 的数据。我们发现各个数据集所建议的物理参数存在显着差异。红外干涉测量数据（约十分之一 AU）所暗示的内盘半径大小比平盘模型的预期要大。在考虑更复杂的磁盘模型（包括磁盘中存在热的内部区域或壁）的情况下讨论这种差异。
We present circumstellar disk models for two pre-main-sequence objects, T Tau and SU Aur. The models are based on interferometric data from infrared and millimeter wavelengths and infrared photometry from the literature. The physical properties of the disk are examined by calculating parameter probabilities based on a passive, flat-disk model. The model adequately fits the data for SU Aur but not for T Tau. We find that there are significant differences in the physical parameters suggested by the individual data sets. The size of the inner disk radius as implied by the infrared interferometry data (~tenths of AU) is larger than expected for a flat-disk model. This discrepancy is discussed in consideration of more complex disk models that include the presence of a hot, inner region or wall in the disk.
