Research Interests

My current research topic is on the molecular outflows in low mass star formation. I am interested in understanding the physical process underlying the observed outflow systems. In particular the role of magnetic field, its effect on jet kinematics appearance, the formation of knots and the ejection history of the jet etc..

I have been analyzing a set of SMA data toward a molecular outflow driven by the Class 0 protostar IRAS 04166+2706 in Taurus. An interesting kinematic pattern was discovered in its extremely high velocity (EHV) jet component in previous work by others. Our follow-up high angular resolution observation with the SMA examine the source in greater detail. A paper summarizing the results was recently accepted by ApJ.

To understand and study the observed kinematic of outflow phenomenon, I have also been running numerical simulations with an MHD code (ZEUS) and try to analyse the results. An important connection between the model/simulation and the observations lies in the chemical composition and its evolution. A future step would be to study the thermal-chemical process and the molecule formation in the wind environment by applying chemical model calculation.
