We made mid-infrared observations of the 10Msun Herbig Be star HD200775 with the Cooled Mid-Infrared Camera and Spectrometer (COMICS) on the 8.2m Subaru Telescope. We discovered di…
IRAS 16293: A "Magnetic" Tale of Two Cores
Ramprasad Rao, Josep Miquel Girart, Daniel P. Marrone +2
We present polarization observations of the dust continuum emission from IRAS 16293 which is a Class 0 protostar and is known to have at least two components, source A and B. These…
Outflows and Massive Stars in the protocluster IRAS 05358+3543
Adam G. Ginsburg, John Bally, Chi-Hung Yan +1
We present new near-IR H2, CO J=2-1, and CO J = 3-2 observations to study outflows in the massive star forming region IRAS 05358+3543. The Canada-France-Hawaii Telescope H2 images…
Testing the Accretion Flow with Plasma Wave Heating Mechanism for Sagittarius a* by the 1.3MM Vlbi Measurements
Lei Huang, Rohta Takahashi, Zhi-Qiang Shen
The vicinity of the supermassive black hole associated with the compact radio source Sagittarius (Sgr) A* is believed to dominate the observed emission at wavelengths near and shor…
The Hot and Clumpy Molecular Cocoon Surrounding the Ultracompact HII Region G5.89-0.39
Y. -N. Su, S. -Y. Liu, K. -S. Wang +2
We present observations of CH3CN (12-11) emission at a resolution of 2" toward the shell-like ultracompact HII region G5.89-0.39 with the Submillimeter Array. The integrated CH3CN…
Polarized Emission of Sagittarius A*
Lei Huang, Siming Liu, Zhi-Qiang Shen +4
We explore the parameter space of the two temperature pseudo-Newtonian Keplerian accretion flow model for the millimeter and shorter wavelength emission from Sagittarius A*. A gene…
Dust coagulation in star formation with different metallicities
Hiroyuki Hirashita, Kazuyuki Omukai
Dust grains coagulate into larger aggregates in dense gas. This changes their size distribution and possibly affects the thermal evolution of star-forming clouds. We here investiga…
On the theory of astronomical maser. II. Polarization of maser radiation
Dinh-V-Trung
In this paper we investigate the polarization property of the radiation amplified by astronomical masers in the presence of a strong magnetic field. Our model explicitly takes into…
On the theory of astronomical maser. I. Statistics of maser radiation
Dinh-V-Trung
In this paper we re-analyse the amplification process of broadband continuum radiation by astronomical masers in one-dimensional case. The basic equations appropriate for the scala…
Explosive Disintegration of a Massive Young Stellar System in Orion
Luis A. Zapata, Johannes Schmid-Burgk, Paul T. P. Ho +2
Young massive stars in the center of crowded star clusters are expected to undergo close dynamical encounters that could lead to energetic, explosive events. However, there has so…
The variability of Sagittarius A* at 3 millimeter
Juan Li, Zhi-Qiang Shen, Atsushi Miyazaki +5
We have performed monitoring observations of the 3-mm flux density toward the Galactic Center compact radio source Sgr A* with the Australia Telescope Compact Array since 2005 Octo…
Rotation and Outflow motions in the very low-mass Class 0 protostellar system HH 211 at subarcsecond resolution
Chin-Fei Lee, Naomi Hirano, Aina Palau +4
HH 211 is a nearby young protostellar system with a highly collimated jet. We have mapped it in 352 GHz continuum, SiO (J=8-7), and HCO+ (J=4-3) emission at up to ~ 0.2" resolution…
