Welcome to the homepage of Hui Tian. I am a researcher working in the fields of space and solar physics, with an emphasis on UV spectroscopy of the Sun. My research interest includes solar transition region dynamics, coronal heating, solar wind origin, magnetic reconnection in solar flares and solar wind, dynamics and magnetism of coronal mass ejections.
IRIS was launched on June 27 2013. It is now obtaining UV spectra and images of the solar transition region and chromosphere with very high resolution in space (0.33-0.4 arcsec) and time (1s).
