Near-infrared imaging polarimetry of bipolar nebulae. 4: GL-490, GL-2789, GL-2136
(1991)
High spatial resolution near-IR polarization and surface brightness images of the ouflow sources GL 490, GL 2789 and GL 2136 are presented. Polarization vector-maps at J, H and K show centro-symmetric patterns around GL ...
Near-infrared imaging polarimetry of bipolar nebulae 1:the BN-KL region of OMC-1
(1991)
New high-spatial-resolution polarization images of the BN-KL region of OMC-1 from 1.25-3.6 microns are presented. At the longer wavelengths these show a centro-symmetric polarization vector pattern, centered mainly on IRc2, ...
Near-infrared imaging polarimetry of bipolar nebulae. 3: R-Mon/NGC-2261
(1991)
High-spatial-resolution polarization vector maps of NGC 2261 at J, H and K show a centrosymmetric pattern, suggesting that it is a near-infrared reflection nebula, illuminated by R Mon. Evidence indicates that R Mon is ...
