研究领域

Project 1: Chinese Hα Solar Explorer (CHASE)

The Chinese Hα Solar Explorer (CHASE), dubbed Xihe -- Goddess of the Sun, was launched on October 14, 2021 as the first solar space mission of China National Space Administration (CNSA). The CHASE mission is designed to test a new satellite platform and conduct solar observations. The scientific payload of the CHASE mission is an Hα Imaging Spectrograph (HIS) which acquires spectroscopic observations at Hα (655.97 - 656.59 nm) and Fe I (656.78 - 657.06 nm) wavebands. A full-Sun scanning takes ~46 seconds, with a spectral sampling of 0.0024 nm and a spatial resolution of 1.2 arcsec. The science data are available to the community through the Solar Science Data Center of Nanjing University (SSDC-NJU, https://ssdc.nju.edu.cn).

Project 2:Solar energetic particles (SEPs)

SEPs, with energies from a few keV to several GeV, are produced by the release of magnetic energy on the Sun, notably flares and coronal mass ejections (CMEs). What I am interested is to clarify where and how SEPs are accelerated and to understand the processes of propagation for different species of SEPs.

Project 3: SOC processes in astrophysics

The power-law frequency distributions are ubiquitous in the Universe. Self-organized criticality (SOC) and turbulence are the two intrinsic physical processes during the energy release in a nonlinear dynamical system. Both of them can produce eruptive events with power laws. What I am interested is to understand the roles of SOC and turbulence in astrophysical eruptions.
