Welcome to my webpage. Here you will find more about my research and me.

I am currently a project researcher in the Kavli Insititute for the Mathematics and Physics of the Universe (IPMU), The University of Tokyo.

My major research is supernova physics by using my multi-dimensional hydrodynamics code.

I finished my PhD in the Chinese University of Hong Kong, with the thesis titled "Dark-matter admixed Stellar Objects".

My research interest:

I am interested in the dynamical processes in stars. Currently, I do multi-dimensional hydrodynamics simulations of the supernova explosion using my multi-D hydrodynamics code, which I developed for my PhD thesis project. Then I calculate the nucleosynthesis yield. By comparing with observational data, I can

·       Predict the supernova progenitors

·       Constrain global properties of supernovae

·       Derive constraints on supernova physics

 

The current research covers the following classes of supernovae:

·       Type Ia supernova

·       Electron capture supernova

·       Core-collapse supernova (Jet-induced explosion)

·       Pulsation pair-instability supernova

 

Among all these supernovae, which explode for very different reasons, I am interested in how they contribute to the chemical diversity of the universe. Currently the sources of observational data come from

·       Supernova light curve and spectra (esp. Type Ia supernova)

·       Solar abundance

·       Well observed galactic clusters (e.g. Perseus clusters) and galaxies

·       Metal-poor stars (esp. CEMP stars)
