Spectropolarimetry of Extremely Luminous Type Ia Supernova 2009dc: Nearly Spherical Explosion of Super-Chandrasekhar Mass White Dwarf
Masaomi Tanaka, Koji S. Kawabata, Masayuki Yamanaka +8
We present the first spectropolarimetric observations of a candidate of super-Chandrasekhar mass Type Ia supernova (SN): SN 2009dc. The observations were performed at 5.6 and 89.5…
Structure and Population of the Andromeda Stellar Halo from a Subaru/Suprime-Cam Survey
M. Tanaka, M. Chiba, Y. Komiyama +3
We present a photometric survey of the stellar halo of the Andromeda galaxy, using Suprime-Cam on the Subaru Telescope. A detailed analysis of VI color-magnitude diagrams of the re…
A massive disk galaxy at z>3 along the sightline of QSO 1508+5714
Yiping Wang, Toru Yamada, Ichi Tanaka +1
We have obtained deep images in the BVRIJHKs bands of the field centered on QSO 1508+5714 (z_{em} =4.28) with the Suprime camera, FOCAS and MOIRCS cameras on Subaru telescope. We r…
Direct Observation of the Extended Molecular Atmosphere of o Cet by Differential Spectral Imaging with an Adaptive Optics System
Hideki Takami, Miwa Goto, Wolfgang Gaessler +13
We present new measurements of the diameter of o Cet (Mira) as a function of wavelength in the 2.2 micron atmospheric window using the adaptive optics system and the infrared camer…
