An H I absorption line survey of Messier 31
The 21-cm absorption through the disk of M31 has been observed, using the VLA to study the cool atomic phase of the interstellar medium in this nearby spiral galaxy. It is found that the abundance of diffuse clouds with ...
EXO 023432-5232.3 - an eclipsing AM Herculis binary
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 ...
Polarimetric observations of the quasar 3C-345
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
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 ...
Infrared reflection nebula in W75N
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
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 ...
