Recently, Prof. ZHAO Yinghe from Yunnan Observatories of the Chinese Academy of Sciences and his collaborators reported research progress on the properties of star formation and interstellar medium for the submillimeter galaxy (SMG) LESS 073, which lies at a redshift of z=4.755 (when the universe is only about 1/11 of the current age).
Dr. MEI Zhixing from Yunnan Observatories of the Chinese Academy of Sciences and his colleagues presented a high-resolution 3D magnetohydrodynamics (MHD) numerical simulation to investigate bimodality nature of the extreme ultraviolet (EUV) disturbances in the corona during eruption of the solar prominence/filament.
An international Astrometry project, named Bar and Spiral Structure Legacy (BeSSeL), investigated the structure of the Milky Way with the technology called VLBI maser astrometry in the past of 15 years. Recently, a study shared a new view o the Milk Way.
Using high-quality Hα observations from the New Vacuum Solar Telescope (NVST), Dr. LI Ting from the National Astronomical Observatories of China and other partners reported apparent fan-shaped jets generated during the interaction between primary fan-shaped jets and nearby facula magnetic structure for the first time.
ZHANG Xinyi, LI Yan, WU Tao, and SU Jie from Yunnan Observatories of the Chinese Academy of Sciences reported a theoretical study on the red giant KIC 9970396. They determined the size of the helium core of red giant KIC 9970396 by asteroseismology. This is the first time that a giant red star whose evolutionary state is located near RGB bumps can obtain accurate helium core size as well as its internal structure through asteroseismology.
Dr. DAI Zhibin from Yunnan Observatories of the Chinese Academy of Sciences and the collaborators reported progress on a candidate of cataclysmic variable star KZ Gemini. They identified the authentic coordinates of KZ Gemini, and achieved a complete analysis on the white dwarf accretion.
