Resistive MHD Simulations of Star-Disk-Jet System (2009)
Cemeljic, Miljenko, Shang, Hsien, Chiang, Tzu-Yang
Stellar magnetosphere and accretion disk interact, and a result should be outflow launched from the innermost vicinity of a protostellar object. We simulated physical conditions in this region by...

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 with the...
First Confirmed Detection of a Bipolar Molecular Outflow from a Young Brown Dwarf (2008)
Phan-Bao, Ngoc, Riaz, Basmah, Lee, Chin-Fei, Tang, Ya-Wen, Ho, Paul T. P., Martin, Eduardo L., ...
Studying the earliest stages in the birth of stars is crucial for understanding how they form. Brown dwarfs with masses between that of stars and planets are not massive enough to maintain stable...
Cai, Mike J., Shang, Hsien, Lin, Hsiao-Hsuan, Shu, Frank H.
The interaction of accretion disks with the magnetospheres of young stars can produce X-winds and funnel flows. With the assumption of axial symmetry and steady state flow, the problem can be...
Submillimeter arcsecond-resolution mapping of the highly collimated protostellar jet HH 211 (2007)
Lee, Chin-Fei, Ho, Paul T. P., Palau, Aina, Hirano, Naomi, Bourke, Tyler L., Shang, Hsien, ...
We have mapped the protostellar jet HH 211 in 342 GHz continuum, SiO ($J=8-7$), and CO ($J=3-2$) emission at $\sim$ \arcs{1} resolution with the Submillimeter Array (SMA). Thermal dust emission is...
HH 212: SMA Observations of a Remarkable Protostellar Jet (2007)
Lee, Chin-Fei, Ho, Paul T. P., Beuther, Henrik, Bourke, Tyler L., Hirano, Naomi, Shang, Hsien, ...
HH 212 is a nearby (460 pc) protostellar jet discovered in H$_2$ powered by a Class 0 source, IRAS 05413-0104, in the L1630 cloud of Orion. It is highly collimated and symmetric with matched pairs of...
HH 212: Submillimeter Array observations of a remarkable protostellar jet (2007)
Lee, Chin-Fei, Ho, Paul T. P., Hirano, Naomi, Beuther, Henrik, Bourke, Tyler L., Shang, Hsien, ...
HH 212 is a nearby (460 pc) protostellar jet discovered in H2 powered by a Class 0 source, IRAS 05413-0104. We have mapped it in 850 mum continuum, SiO(J=8-7), CO(J=3-2), SO(NJ=89-78), HCO+(J=4-3),...
Infall and outflow around the HH 212 protostellar system (2006)
Lee, Chin-Fei, Ho, Paul T. P., Beuther, Henrik, Bourke, Tyler L., Zhang, Qizhou, Hirano, Naomi, ...
HH 212 is a highly collimated jet discovered in H2 powered by a young Class 0 source, IRAS 05413-0104, in the L1630 cloud of Orion. We have mapped around it in 1.33 mm continuum, 12CO (J=2-1), 13CO...
The Irradiation Origin of Beryllium Radioisotopes and Other Short-lived Radionuclides (2005)
Gounelle, Matthieu, Shu, Frank H., Shang, Hsien, Glassgold, A. E., Rehm, K. E., Lee, Typhoon
Two explanations exist for the short-lived radionuclides present in the solar system when the CAIs first formed. They originated either from the ejecta of a supernova or by the in situ irradiation of...
SiO J=5--4 in the HH211 Protostellar Jet Imaged with the SMA (2005)
Hirano, Naomi, Liu, Sheng-Yuan, Shang, Hsien, Ho, Paul T. P., Huang, Hui-Chun, Kuan, Yi-Jehng, ...
We have mapped the SiO J=5-4 line at 217GHz from the HH211 molecular outflow with the Submillimeter Array (SMA). The high resolution map (1.6''x0.9'') shows that the SiO J=5-4 emission comes from the...

Structure and Physical Conditions in MHD Jets from Young Stars (2001)
We have constructed the foundations to a series of theoretical diagnostic methods to probe the jet phenomenon in young stars as observed at various optical forbidden lines. We calculate and model in...
