Spitzer IRAC and MIPS Imaging of Clusters and Outflows in 9 High-mass Star Forming Regions
Keping Qiu, Qizhou Zhang, S. Thomas Megeath +6
We present Spitzer Space Telescope IRAC and MIPS observations toward a sample of nine high-mass star forming regions at a distance of around 2 kpc. Based on IRAC and MIPS 24 m p…
SMA Imaging of CO(3-2) Line and 860 micron Continuum of Arp 220 : Tracing the Spatial Distribution of Luminosity
Kazushi Sakamoto, Junzhi Wang, Martina C. Wiedner +6
We used the Submillimeter Array (SMA) to image 860 micron continuum and CO(3-2) line emission in the ultraluminous merging galaxy Arp 220, achieving a resolution of 0.23" (80 pc) f…
An evolved disk surrounding the massive main sequence star MWC 297?
P. Manoj, Paul T. P. Ho, Nagayoshi Ohashi +5
We present the results of the interferometric observations of the circumstellar disk surrounding MWC 297 in the continuum at 230 GHz (1.3 mm) and in the (J=2-1) rotational transiti…
Submillimeter arcsecond-resolution mapping of the highly collimated protostellar jet HH 211
Chin-Fei Lee, Paul T. P. Ho, Aina Palau +4
We have mapped the protostellar jet HH 211 in 342 GHz continuum, SiO (), and CO () emission at \arcs{1} resolution with the Submillimeter Array (SMA). Thermal…
The Early Evolution of Massive Stars: Radio Recombination Line Spectra
Eric Keto, Qizhou Zhang, Stanley Kurtz
Velocity shifts and differential broadening of radio recombination lines are used to estimate the densities and velocities of the ionized gas in several hypercompact and ultracompa…
A Jet-like Outflow toward the High-Mass (Proto)stellar Object IRAS 18566+0408
Qizhou Zhang, T. K. Sridharan, Todd R. Hunter +3
We performed interferometric observations of a high-mass protostellar candidate IRAS 18566+0408 in the \nh3 (J,K)=(1,1), (2,2) and (3,3) inversion transitions, the SiO J=2-1 and HC…
