We present new high-resolution (∼0. ′′09) H-band imaging observations of the circumstellar disk around the T Tauri star SU Aur. Our observations with Subaru-HiCIAO have revealed the presence of scattered light as close as 0. ′′15 (∼20 AU) to the star. Within our image, we identify bright emission associated with a disk with a minimum radius of ∼90 AU, an(More)
A high angular resolution near-infrared polarized-intensity image of the GG Tau A binary system was obtained with the Subaru Telescope. The image shows the circumbinary disk scattering the light from the central binary. The azimuthal profile of the polarized intensity of the circumbinary disk is roughly reproduced by a simple disk model with the(More)
We have conducted a systematic near-infrared circular polarization (CP) survey in star-forming regions, covering high-mass, intermediate-mass, and low-mass young stellar objects. All the observations were made using the SIRPOL imaging polarimeter on the Infrared Survey Facility 1.4 m telescope at the South African Astronomical Observatory. We present the(More)
Pazopanib is a potent multitargeted tyrosine kinase inhibitor that has been shown to have good efficacy in patients with renal cell carcinoma. A previous phase II trial demonstrated that short-term pazopanib administration was generally well tolerated and showed antitumor activity in patients with early-stage non-small cell lung cancer. Herein, we report on(More)
We present the first spatially resolved polarized scattered light H-band detection of the DoAr 28 transitional disk. Our two epochs of imagery detect the scattered light disk from our effective inner working angle of 0. ′′10 (13 AU) out to 0. ′′50 (65 AU). This inner working angle is interior to the location of the system’s gap inferred by previous studies(More)
Dust trapping accelerates the coagulation of dust particles, and thus it represents an initial step toward the formation of planetesimals. We report H-band (1.6 μm) linear polarimetric observations and 0.87 mm interferometric continuum observations toward a transitional disk around LkHα 330. As results, a pair of spiral arms were detected in the H-band(More)
