Grain alignment in dense interstellar environments : spectropolarimetry of the 4.67-m CO-ice feature in the field star Elias 16 (Taurus dark cloud)
(2008)
We present spectropolarimetry of the solid CO feature at 4.67 μm along the line of sight to Elias 16, a field star background to the Taurus dark cloud. A clear increase in polarization is observed across the feature with ...
An Extended Search for Circularly Polarized Infrared Radiation from the OMC-1 Region of Orion
(2005-05)
We present new observations of circular polarization (CP) at 2.2 m in the Orion (OMC-1) molecular cloud. Our results extend a previously published study of the region.We show that the degree of CP correlates spatially with ...
UV Circular Polarisation in Star Formation Regions : The Origin of Homochirality?
(2005-02)
Ultraviolet circularly polarised light has been suggested as the initial cause of the homochirality of organic molecules in terrestrial organisms, via enantiomeric selection of prebiotic molecules by asymmetric photolysis. ...
Spectropolarimetry of the 3.4 m Band in the Quintuplet
(Astronomical Society of the Pacific, 2005)
We present spectropolarimetry of the 3.4?m solid hydrocarbon absorption feature arising in the ISM toward the Quintuplet member GCS3-II, permitting for the first time a comparison of the hydrocarbon and silicate polarizations ...
Opportunities for Imaging and Spectro-Polarimetry at UKIRT
(Astronomical Society of the Pacific, 2005)
Near-IR imaging and spectro-polarimetry are offered with the facility instruments UIST and UFTI. Both linear and circular polarimetry are possible, the former from 1-5¹m, the latter from 1-2.5¹m. The IRPOL polarimetry ...
