Near-infrared circular polarimetry and correlation diagrams in the Orion Becklin-Neugebauer/Kleinman-low region: contribution of dichroic extinction
(2009)
We present a deep circular polarization (CP) image of the Orion Becklin-Neugebauer (BN)/Kleinman-Low (KL)nebula in the K-s band and correlations of CP, linear polarization (LP) and H-K-s color representing extinction. The ...
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 ...
The efficiency of grain alignment in dense interstellar clouds: : a reassessment of constraints from near-infrared polarization
(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 ...
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 ...
