A Re-examination of the Star Observation in Early Ming Dynasty Based on the Star Catalogue of \textit{Datong Tongzhan}-with Discussion on the Changes of Traditional Chinese Constellations
Chu, L. F.; Yang, B. S.
\textit{Datong Tongzhan} is a divination book compiled by the Imperial Board of Astronomy in early Ming dynasty, which preserves some positional data of stars observed at that time. Based on this star catalogue, a further research is carried out on star observation in early Ming dynasty. Firstly, through a deep analysis, it is found that this book…
Multi-wavelength and Multi-perspective Studies of Coronal Mass Ejections and Their Driven Shocks
Ying, B. L.
Coronal Mass Ejections (CMEs) are one of the most fierce explosion phenomena in the solar atmosphere. CMEs usually release a large amount of energy and eject massive magnetized plasma. CME-driven shocks can further lead to solar energetic particle (SEP) events and affect the safety of spacecraft and astronauts. Therefore, researches on CME initiat…
Multi-star System Observations Based on the Direct-imaging Method
Zhao, G.; Chen, Y. L.; Zhu, Y. T. +1 more
The direct-imaging exploration can obtain comprehensive physical information of exoplanets, which is a key technology to search for extraterrestrial life in the future. In this paper, based on our recent high-contrast imaging data of ground-based telescope, the newly discovered multi-star candidates are presented. In the early stage, combined with…
