Infall and outflow detections in a massive core JCMT 18354-0649S
Tie Liu, Yuefang Wu, Qizhou Zhang +3
We present a high-resolution study of a massive dense core JCMT 18354-0649S with the Submillimeter Array. The core is mapped with continuum emission at 1.3 mm, and molecular lines…
Outflows, Accretion, and Clustered Protostellar Cores around a Forming O Star
Keping Qiu, Qizhou Zhang, Karl M. Menten
We present a Submillimeter Array study in the 1.3 mm waveband of the NGC 7538 IRS 1--3 massive star-forming region. The brightest core in the mm continuum map, MM1, harbors the IRS…
Is protostellar heating sufficient to halt fragmentation? A case study of the massive protocluster G8.68-0.37
Steven N. Longmore, Thushara Pillai, Eric Keto +2
If star formation proceeds by thermal fragmentation and the subsequent gravitational collapse of the individual fragments, how is it possible to form fragments massive enough for O…
High Velocity Molecular Outflows In Massive Cluster Forming Region G10.6-0.4
Hauyu Baobab Liu, Paul T. P. Ho, Qizhou Zhang
We report the arcsecond resolution SMA observations of the CO (2-1) transition in the massive cluster forming region G10.6-0.4. In these observations, the high velocity $^{1…
The magnetic field in the NGC 2024 FIR 5 dense core
Felipe de O. Alves, Josep M. Girart, Shih-Ping Lai +2
We used the Submillimeter Array (SMA) to observe the thermal polarized dust emission from the protostellar source NGC 2024 FIR 5. The polarized emission outlines a partial hourglas…
The Decrease of Specific Angular Momentum and the Hot Toroid Formation: The Massive Clump G10.6-0.4
Hauyu Baobab Liu, Paul T. P. Ho, Qizhou Zhang +3
This is the first paper of our series of high resolution (1") studies of the massive star forming region G10.6--0.4. We present the emission line observations of the hot core type…
IRAS 22198+6336: Discovery of an Intermediate-Mass Hot Core
Alvaro Sanchez-Monge, Aina Palau, Robert Estalella +4
We present new SMA and PdBI observations of the intermediate-mass object IRAS 22198+6336 in the millimeter continuum and in several molecular line transitions. The millimeter conti…
Clouds, filaments and protostars: the Herschel Hi-GAL Milky Way
S. Molinari, B. Swinyard, J. Bally +121
We present the first results from the science demonstration phase for the Hi-GAL survey, the Herschel key-project that will map the inner Galactic Plane of the Milky Way in 5 bands…
A large, massive, rotating disk around an isolated young stellar object
Sascha P. Quanz, Henrik Beuther, Juergen Steinacker +5
We present multi-wavelengths observations and a radiative transfer model of a newly discovered massive circumstellar disk of gas and dust which is one of the largest disks known to…
L1448 IRS2E: A candidate first hydrostatic core
Xuepeng Chen, Hector G. Arce, Qizhou Zhang +4
Intermediate between the prestellar and Class 0 protostellar phases, the first core is a quasi-equilibrium hydrostatic object with a short lifetime and an extremely low luminosity.…
From the Convergence of Filaments to Disk-Outflow Accretion: Massive-Star Formation in W33A
Roberto Galván-Madrid, Qizhou Zhang, Eric Keto +5
Interferometric observations of the W33A massive star-formation region, performed with the Submillimeter Array (SMA) and the Very Large Array (VLA) at resolutions from 5 arcsec (0.…
The standard model of star formation applied to massive stars: accretion disks and envelopes in molecular lines
Eric Keto, Qizhou Zhang
We address the question of whether the formation of high-mass stars is similar to or differs from that of solar-mass stars through new molecular line observations and modeling of t…
Deuterium Fractionation as an Evolutionary Probe in the Infrared Dark Cloud G28.34+0.06
Huei-Ru Chen, Sheng-Yuan Liu, Yu-Nung Su +1
We have observed the J=3-2 transition of N2H+ and N2D+ to investigate the trend of deuterium fractionation with evolutionary stage in three selected regions in the Infrared Dark Cl…
The reflection-symmetric wiggle of the young protostellar jet HH 211
Chin-Fei Lee, Tatsuhiko I. Hasegawa, Naomi Hirano +4
HH 211 is a highly collimated jet originating from a nearby young Class 0 protostar. Here is a follow-up study of the jet with our previous observations at unprecedented resolution…
