标题： The Circumstellar Matter Around OH44.8-2.3

摘要： 给出了OH激射体源OH44.8-2.3的I波段图像。由于该天体的距离已精确测定，因此表明它非常年轻且物理尺寸很小，同时已经存在一个不对称的致密双极星云。按照Meixner等人（2000）和Ueta等人（2000）的形态学术语，由于其高光学深度和极地到赤道的密度对比，该天体将被归类为DUPLEX星云。 显示英文摘要

摘要： I-band images of the OH maser source OH44.8-2.3 are presented. Having a well-determined distance, this object is shown to be very young and physically small, with an asymmetric compact bipolar nebula already present. In the morphological terminology of Meixner et al. (2000) and Ueta et al. (2000), this object would be classified as a DUPLEX nebula because of its high optical depth and pole-to-equator density contrast.
