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 ...
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 ...
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 ...
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 ...
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 ...
Interstellar polarization in the dust lane of Centaurus A (NGC 5128)
(1987)
Optical and infrared linear polarization measurements of the Type 1 supernova 1986G in Centaurus A are used to determine the wavelength dependence of polarization produced by transmission of radiation through the dust lane ...
Infrared spectropolarimetry of the galactic-center-magnetic alignment in the discrete sources
(1986)
The results of 8-13 micron spectropolarimetric observations of Galactic Center sources are presented. All the sources show interstellar polarization due to absorption by aligned silicate grains, and these grains appear to ...
Infrared polarimetry of the nucleus of Centaurus A - The nearest blazar?
(1986)
As one of the nearest examples of an active galaxy, NGC5128 (Centaurus A) has been studied in detail over a wide range of wavelengths. The nucleus of the galaxy is seen clearly in the X-ray, radio and infrared, but is ...
Infrared photometry of the nuclei of early-type radio galaxies
(1986)
The authors have obtained near- and mid-infrared photometry of the nuclei of both strong and weak radio galaxies. The implication of these data are that a relatively small percentage, ≅15 per cent, of radio ellipticals ...
