Iron Fluorescent Line Emission from Young Stellar Objects in the Orion Nebula
M. Tsujimoto, E. D. Feigelson, N. Grosso +5
We present the result of a systematic search for the iron Kalpha fluorescent line at 6.4 keV among 1616 X-ray sources detected by ultra-deep Chandra observations of the Orion Nebul…
Chandra Observation of the Starburst Galaxy NGC 2146
Tatsuya Inui, Hironori Matsumoto, Takeshi Go Tsuru +4
We present six monitoring observations of the starburst galaxy NGC 2146 using the Chandra X-ray Observatory. We have detected 67 point sources in the 8'.7 x 8'.7 field of view of t…
The Surprisingly Steep Mass Profile of Abell 1689, from a Lensing Analysis of Subaru Images
Tom Broadhurst, Masahiro Takada, Keiichi Umetsu +4
Subaru observations of A1689 (z=0.183) are used to derive an accurate, model-independent mass profile for the entire cluster, r<2 Mpc/h, by combining magnification bias and distort…
Hot Jupiters and Hot Spots: The Short- and Long-term Chromospheric Activity on Stars with Giant Planets
E. Shkolnik, G. A. H. Walker, D. A. Bohlender +2
We monitored the chromospheric activity in the Ca II H & K lines of 13 solar-type stars (including the Sun); 8 of them over three years at the CFHT and 5 in a single run at the VLT…
Starburst at the Expanding Molecular Superbubble in M82: Self-Induced Starburst at the Inner Edge of the Superbubble
Satoki Matsushita, Ryohei Kawabe, Kotaro Kohno +3
We present high spatial resolution (2.3"x1.9" or 43 pc x 36 pc at D = 3.9 Mpc) 100 GHz millimeter-wave continuum emission observations with the Nobeyama Millimeter Array toward an…
Organic Molecules in Low-Mass Protostellar Hot Cores: Submillimeter Imaging of IRAS 16293-2422
Y. -J. Kuan, H. -C. Huang, S. B. Charnley +8
Arcsecond-resolution spectral observations toward the protobinary system IRAS 16293-2422 at 344 and 354 GHz were conducted using the Submillimeter Array. Complex organic molecules…
