主要研究方向：Accreting compact objects and its cosmological applications; Graviton in neutron star binary systems
My research experiences theoretical physics (cosmology), compact objects (accreting neutron star), and high-energy (X-ray) astronomical observations. I started my research career from cosmology at IHEP, CAS. Motivated by the idea that the extreme conditions offered by compact objects provide unique natural laboratory to investigate the behavior of particles in strong fields and thus the early universe, I turned into compact objects for doctoral dissertation, during which I comprehensively studied accretion process in the inner accretion disk of neutron star low-mass X-ray binaries (LMXBs). When I worked for the theoretical research, I realized that the excellent theoretical work should tightly follow observations. I extend my research to observational astronomy and work for X-ray data analysis since I worked as a postdoctoral research fellow at NTHU, during which I (1) proposed reversal wind accretion theory to explain the formation mechanism of SFXT, (2) proposed quasi-quantized disk structure of accreting neutron star in LMXBs which will be used to study X-ray polarization and CPT, (3) investigated the energy dependence of low frequency QPOs and determined its emission site, (4) I also extend my theoretical research to fundamental physics in strong fields.
I currently investigate the mass generation of graviton due to scalarization in neutron star binaries during gravitational radiation. My future research work will focus on accretion astrophysics of compact objects in X-ray binaries. On the one hand, I will keep on my previous study on accretion physics of compact objects. On the other hand, I will extend the accretion to new issue, i.e. investigate the dark side of universe, by means of accretion of compact objects.
Accreting compact objects in binary systems:
(1) Eddington-accretion regime —investigate the inner disk structure of accreting NS/BH by using QPO observations, then further study X-ray polarization and Lorentz invariance or violation in strong fields; (2) Super-Eddington accretion —the coupling of accretion flow onto magnetic field in wind-fed and disk-fed systems and the possible catastrophic results
(2) Nature of dark energy and candidate of dark matter by studying accretion process of compact objects
