我们提出了新的高空间分辨率近红外（和窄带L）成像偏振的有趣的双极星云NGC 6334 V的偏振矢量的图案表明，该地区比以前认为的更复杂。在西瓣，偏振矢量的中心对称图案是由外流中的反射产生的，其中IRS V3是最可能的源。然而，东叶似乎并不反映这种模式。这可能是由于IRS V3周围存在偏振盘，其破坏了东瓣中的偏振图案。在另一种情况下，源IRS V1和V2，其发射主导了东叶，位于双极星云的前景，并有助于在这个叶的整体反射星云。后一种结构与以前的模型相反，在以前的模型中，两个叶被认为是单个流出的一部分。
We present new high spatial resolution near-infrared (and narrow-bandL) imaging polarimetry of the interesting bipolar nebula NGC 6334 V. The pattern of polarization vectors demonstrates that the region is more complicated than previously believed. In the western lobe, the centro-symmetric pattern of polarization vectors is produced by reflection in an outflow, for which IRS V3 is the most likely source. The eastern lobe, however, does not appear to reflect this pattern. This could be due to the presence of a polarization disc around IRS V3 which disrupts the polarization pattern in the eastern lobe. In an alternative scenario, the sources IRS V1 and V2, whose emission dominates the eastern lobe, are located in the foreground of the bipolar nebula and contribute to the overall reflection nebulosity in this lobe. This latter structure is contrary to previous models in which both lobes were considered to be part of a single outflow.
