Spectropolarimetry of the 3-micron ice feature in molecular clouds. II : GL 2591, GL 2136, W 33A and Elias 29 (Rho Ophiuchi dark cloud)
(1989)
Spectropolarimetric observations in the 3-micron ice band are presented for the infrared sources GL 2591, GL 2136, W 33A and Elias 29 (Rho Ophiuchi dark cloud). Some continuum polarization measurements between 1.2 and 5.0 ...
Polarimetric observations of the quasar 3C-345
(1988)
Infrared and optical polarimetric observations of the quasar 3C 345 are presented, which show a decrease in the degree of polarization with frequency previously observed by Smith et al., and interpreted by them as the ...
Photometry and polarimetry of AM Herculis in its faint state
(1988)
Infrared and optical photometry and polarimetry of AM Herculis during the faint state of its long-term light variations are presented. The contributions of the two stellar photospheres are estimated and the distance of the ...
EXO 023432-5232.3 - an eclipsing AM Herculis binary
(1988)
The authors report observations of the serendipitous EXOSAT source EXO 023432-5232.3 which confirm that the object is an AM Herculis type binary and show the presence of eclipses by the companion star. From high-speed ...
Infrared polarimetry of dark clouds. II : Magnetic field structure in the Rho Ophiuchi dark cloud
(1988)
K-band polarimetry of 20 sources embedded within the densest region of the Rho Oph dark cloud has been obtained. The degree of polarization ranges from 1.1 to 7.4 percent, and the position angles have a bimodal distribution, ...
Spectropolarimetry of the 3-micron ice band in Elias 16 (Taurus Dark Cloud)
(1988)
Polarization data between 1.2 and 3.8 μm, including spectropolarimetry in the 3-μm ice feature, are presented for the highly reddened field star Elias 16 in the Taurus Dark Cloud. The polarization is observed to increase ...
Infrared reflection nebula in W75N
(1988)
A new infrared reflection nebula is identified in the W75N region. The K-band polarization map shows a centrosymmetric pattern of the vectors extending over a region 2 arcmin in size, with large values of degrees of ...
The polarization of NGC 1068
(1988)
Broad-band polarimetry of NGC 1068 over the wavelength range 0.36 - 4.8 μm is presented, together with high-resolution spectropolarimetry of the Hβ, [O III] and Hα, [N II] regions of the spectrum. The authors recognize ...
Spectropolarimetry of the molecular-hydrogen line emission from OMC-1
(1988)
Observations of the H2 v = 1-0 S(1) line at 35 km/s velocity resolution were obtained at several locations within OMC-1, including the molecular hydrogen reflection nebula. All line profiles are smooth and show no evidence ...
