Abstract
We present new high spatial resolution near-infrared (H, K(n) and narr ow-band L) imaging polarimetry of the interesting bipolar nebula NGC 6 334 V. The pattern of polarization vectors demonstrates that the regio n is more complicated than previously believed. In the western lobe, t he centro-symmetric pattern of polarization vectors is produced by ref lection 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 IRSV3 which disrupts the polarization pattern in the eastern lobe. In an alternat ive 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 lat ter structure is contrary to previous models in which both lobes were considered to be part of a single outflow.
