S106在50和100微米的测光，以及它的映射与35角秒分辨率和附近的H2O脉泽源在2和10微米的搜索，产生的数据是一致的900 pc的距离和O9（ZAMS）光谱类型的一个单一的，中央令人兴奋的星星。尘埃温度与光发射的相关性，以及尘埃光学厚度与光发射的关系，支持S106的模型，该模型设想了一个令人兴奋的星星，周围是一个尘埃盘，沿沿着其近似的南北轴具有非常低的光学消光。尘埃柱密度的局部最大值被发现的光学星云的西部，附近的位置的水脉泽，虽然没有当地的近红外或远红外通量的最大值被检测到。
Photometry of S106 at 50 and 100 microns, as well as its mapping with 35 arcsec resolution and a search for a nearby H2O maser source at 2 and 10 microns, have yielded data that are consistent with a 900 pc distance and an O9 (ZAMS) spectral type for a single, central exciting star. The correlation of dust temperature with optical emission, and anticorrelation of dust optical depth with optical emission, support models of S106 which envision an exciting star surrounded by a dusty disk having very low optical extinction along its approximately north-south axis. A local maximum in the dust column density was found to the west of the optical nebula, near the position of an H2O maser, although no local near- or far-IR flux maximum was detected.
