The Suzaku Observations of SS Cygni in Quiescence and Outburst
Manabu Ishida, Shunsaku Okada, Takayuki Hayashi +4
We present results from the Suzaku observations of the dwarf nova SS Cyg in quiescence and outburst in 2005 November. Owing to high sensitivity of the HXD PIN detector and high spe…
Centimeter Polarimetry of the R Coronae Australis Region
Minho Choi, Ken'ichi Tatematsu, Kenji Hamaguchi +1
Circularly polarized 3.5 cm continuum emission was detected toward three radio sources in the R CrA region using the Very Large Array. The Class I protostar IRS 5b persistently sho…
Suzaku and XMM-Newton Observations of Diffuse X-ray Emission from the Eastern Tip Region of the Carina Nebula
Yuichiro Ezoe, Kenji Hamaguchi, Robert A. Gruendl +3
The eastern tip region of the Carina Nebula was observed with the Suzaku XIS for 77 ks to conduct a high-precision spectral study of extended X-ray emission. XMM-Newton EPIC data o…
Resolving a Class I Protostar Binary System with Chandra
Kenji Hamaguchi, Minho Choi, Michael F. Corcoran +3
Using a sub-pixel event repositioning technique, we spatially resolved X-ray emission from the infrared double system IRS 5 in the R Corona Australis molecular cloud with ~0.8" sep…
Centimeter Imaging of the R Coronae Australis Region
Minho Choi, Kenji Hamaguchi, Jeong-Eun Lee +1
The R CrA region was observed in the 3.5 and 6.2 cm continuum with high angular resolutions (0.6--1.7 arcseconds) using the Very Large Array. Archival data sets were also analyzed…
Chandra X-ray Grating Spectrometry of Eta Carinae near X-ray Minimum: I. Variability of the Sulfur and Silicon Emission Lines
D. B. Henley, M. F. Corcoran, J. M. Pittard +3
We report on variations in important X-ray emission lines in a series of Chandra grating spectra of the supermassive colliding wind binary star Eta Carinae, including key phases ar…
