Near-Infrared Imaging Polarimetry of S106 Cluster-Forming Region with SIRPOL
Hiro Saito, Motohide Tamura, Ryo Kandori +7
We present the results of wide-field JHKs polarimetry toward the HII region S106 using the IRSF (Infrared Survey Facility) telescope. Our polarimetry data revealed an extended (up…
Near-Infrared Polarimetry toward the Galactic Center
Shogo Nishiyama, Motohide Tamura, Hirofumi Hatano +4
Near-infrared polarimetry of point sources reveals the presence of a toroidal magnetic field in the central 20' x 20' region of our Galaxy. Comparing the Stokes parameters between…
Millimeter- and Submillimeter-Wave Observations of the OMC-2/3 Region. III. An Extensive Survey for Molecular Outflows
Satoko Takahashi, Masao Saito, Nagayoshi Ohashi +5
Using the ASTE 10 m submillimeter telescope and the 1.4 m Infrared Survey Facility (IRSF), we performed an extensive outflow survey in the Orion Molecular Cloud -2 and -3 region. O…
Near-Infrared Imaging Polarimetry of M42: Aperture Polarimetry of Point-like Sources
Nobuhiko Kusakabe, Motohide Tamura, Ryo Kandori +6
We have conducted aperture polarimetry of ~500 stars of the Orion Nebula Cluster (ONC) in M42 based on our wide-field (~8'\times 8') band polarimetry. Most of the near-infra…
Measurement of the Spin-Orbit Angle of Exoplanet HAT-P-1b
John A. Johnson, Joshua N. Winn, Norio Narita +16
We present new spectroscopic and photometric observations of the HAT-P-1 planetary system. Spectra obtained during three transits exhibit the Rossiter-McLaughlin effect, allowing u…
Fifteen new T dwarfs discovered in the UKIDSS Large Area Survey
D. J. Pinfield, B. Burningham, M. Tamura +32
We present the discovery of fifteen new T2.5-T7.5 dwarfs (with estimated distances between ~24-93pc, identified in the first three main data releases of the UKIRT Infrared Deep Sky…
