Extended High Circular Polarization in the Orion Massive Star Forming Region: Implications for the Origin of Homochirality in the Solar System
(2010)
We present a wide-field (∼6′ × 6′) and deep near-infrared (K s band: 2.14 μm) circular polarization image in the Orion nebula, where massive stars and many low-mass stars are forming. Our results reveal that a high circular ...
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 ...
Planetpol polarimetry of the exoplanet systems 55 Cnc and tau Boo
(2009)
We present very sensitive polarimetry of 55 Cnc and τ Boo in an attempt to detect the partially polarized reflected light from the planets orbiting these two stars. 55 Cnc is orbited by a hot Neptune planet (55 Cnc e) at ...
Low Polarization Standards
(Astronomical Society of the Pacific, 2007)
There is renewed interest in high sensitivity polarimetry as a means of observing the polarization signal of extra-solar planets. We describe the measurement of low polarized standards at fractional polarizations of parts ...
Circular Polarization in Star- Formation Regions : Implications for Biomolecular Homochirality
(1998)
Strong infrared circular polarization resulting from dust scattering in reflection nebulae in the Orion OMC-1 star-formation region has been observed. Circular polarization at shorter wavelengths might have been important ...
Identification of the exciting source of Herbig-Haro objects 135 and 136
(1997)
We have identified the exciting source of the Herbig-Haro objects HH135 and 136 by near-infrared polarimetric imaging of the associated extensive reflection nebula. The source is situated at the middle of the two Herbig-Haro ...
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 ...
