个人简介: 

My current research interests stem from my desire to understand fundamental physics of stars in different stellar evolution stages. These evolution stages are mainly main sequence, subgiant and red giant branch where solar-like oscillations can exist for low-mass stars. I study these stars by employing the method of Asteroseismology, which is the science that studies the internal structure of pulsating stars by the interpretation of their frequency spectra. This tool allows us to probe deep into stars and hence to study the very complex physics beneath the stellar surface, such as the differential rotation, which is unachievable only by observations. My work consists of two parts, modelling and seismic study. As a modeller, I use stellar evolution codes to compute stellar models, which are able to provide global parameters of stars, such as mass, radius, temperature, age and so on, by comparing them with observational constraints. As a theorist, I analyse the oscillation modes of stars theoretically and compare them with observed results in order to extract possible scientific facts that are hidden in those modes. This part also involves another important aspect of my research, which is data analysis.
