Magnetic field configuration at the galactic center investigated by wide-field near-infrared polarimetry : transition from a toroidal to a poloidal magnetic field
(2010)
We present a large-scale view of the magnetic field (MF) in the central 2° × 2° region of our Galaxy. The polarization of point sources has been measured in the J, H, and KS bands using the near-infrared polarimetric camera ...
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 ...
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 ...
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 ...
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 ...
