Distributions of the high velocity SiO (left panel) and CO (right) emission. The velocity ranges are ±51–70km s with respect to the systemic velocity. Green cross in each panel denotes the position of the continuum peak of L1448C(N).
Extreme Active Molecular Jets in L1448C
After its month-long journey from Taiwan, the first of the two Front-End Service Vehicles is being tested at the ALMA Operations Support Facility in Chile. In this photo, the FESV cabin raises to service the interior of a North American ALMA telescope. The first FESV is named Mei-hua after the Taiwanese plum blossom, a revered, winter-blooming flower.

Simulations of our CFW models from 1 to 6, at the age of ~160 yr. Parts (a), (c), (e), (g), (i), and (k) show the number density of hydrogen nuclei in logarithmic scale. Parts (b), (d), (f), (h), (j), and (l) show the temperature in logarithmic scale. The molecular fractions f = 0.1 (white line) and f = 0.49 (magenta line) are shown to outline the distribution of molecular gas. The separation between the AGB wind and the CFW is shown by the color tracer c = 0.5 (gray line, at which half is AGB wind and half is CFW). The CFW is atomic at 10,000 K in models 1 and 2, while is molecular at 1000 K in models 3–6. The CFW is steady in models 1 and 3, while is pulsed with A = 0.5 in models 2 and 4, A = 0.3 in model 5, and A = 0.1 in model 6. Parts (A)−(F) show respectively the blow-ups for the regions in the boxes (A)−(F).

Research Interests

I am interested mainly in the formation and evolution of sunlike stars. With radio observations and magneto-hydrodynamical simulations, I aim to achieve a better understanding of their physical processes. In star formation, I study the gravitational collapse of circumstellar material around protostars (baby stars), and jet and outflow interactions with the surrounding material. In stellar evolution, I study the formation mechanism of proto-planetary and planetary nebulae in order to determine the mass-loss mechanism as sunlike stars die. Hydrogen chemistry and radiative cooling have been added into our numerical codes in order to simulate jet and outflow interactions more realistically.
