Properties of active galactic star-forming regions probed by imaging spectroscopy with the Fourier transform spectrometer (FTS) onboard AKARI
Yoko Okada, Mitsunobu Kawada, Noriko Murakami +8
We investigate the structure of the interstellar medium (ISM) and identify the location of possible embedded excitation sources from far-infrared (FIR) line and mid-infrared contin…
Early phase observations of extremely luminous Type Ia Supernova 2009dc
M. Yamanaka, K. S. Kawabata, K. Kinugasa +31
We present early phase observations in optical and near-infrared wavelengths for the extremely luminous Type Ia supernova (SN Ia) 2009dc. The decline rate of the light curve is $Δm…
BD +44 493: A Ninth Magnitude Messenger from the Early Universe; Carbon Enhanced and Beryllium Poor
Hiroko Ito, Wako Aoki, Satoshi Honda +1
We present a 1D LTE chemical abundance analysis of the very bright (V=9.1) Carbon-Enhanced Metal-Poor (CEMP) star BD +44 493, based on high-resolution, high signal-to-noise spectra…
Spectroscopic Observations of the WZ Sge-Type Dwarf Nova GW Librae during the 2007 Superoutburst
Kazuo Hiroi, Daisaku Nogami, Yoshihiro Ueda +13
We carried out an international spectroscopic observation campaign of the dwarf nova GW Librae (GW Lib) during the 2007 superoutburst. Our observation period covered the rising pha…
Early Spectral Evolution of the Rapidly Expanding Type Ia SN 2006X
Masayuki Yamanaka, Hiroyuki Naito, Kenzo Kinugasa +6
We present optical spectroscopic and photometric observations of Type Ia supernova (SN) 2006X from --10 to +91 days after the -band maximum. This SN exhibits one of the highest…
Doppler-Broadened Iron X-ray Lines from Tycho's Supernova Remnant
A. Furuzawa, D. Ueno, A. Hayato +13
We use \suzaku observations to measure the spatial variation of the Fe K line with radius in the \tycho supernova remnant. The Fe line widths show a significant decrease from a…
