| 1 | First light of the 1.8-m solar telescope–CLST显示文摘Large-aperture solar telescopes play an important role in solar observations and research,and require high temporal and spatial resolution[1].To solve some fundamental problems such as the solar dynamo,coronal heating,and the triggering of major solar eruptions,the spatial resolution for solar-atmosphere observation should reach at least 0.1 arcsec[2]. | ChangHui Rao NaiTing Gu XueJun Rao Cheng Li LanQiang Zhang JinLong Huang Lin Kong Ming Zhang YunTao Cheng Yi Pu Hua Bao YouMing Guo YangYi Liu JinSheng Yang LiBo Zhong ChangJun Wang Kai Fang XiaoJun Zhang DongHong Chen Cheng Wang XinLong Fan ZhiWu Yan KeLe Chen XiYa Wei Lei Zhu Hong Liu YongJian Wan Hao Xian WenLi Ma | 2020 | Science China(Physics,Mechanics & Astronomy)2020，63，10： | 6 |
| 2 | Wind estimation around the shipwreck of Oriental Star based on field damage surveys and radar observations显示文摘Based on observational analyses and on-site ground and aerial damage surveys, this work aims to reveal the weather phenomena—especially the wind situation—when Oriental Star capsized in the Yangtze River on June 1, 2015.Results demonstrate that the cruise ship capsized when it encountered strong winds at speeds of at least 31 m s^(-1) near the apex of a bow echo embedded in a squall line. As suggested by the fallen trees within a 2-km radius around the wreck location,such strong winds were likely caused by microburst straight-line wind and/or embedded small vortices, rather than tornadoes. | Zhiyong Meng Dan Yao Lanqiang Bai Yongguang Zheng Ming Xue Xiaoling Zhang Kun Zhao Fuyou Tian Mingjun Wang | 2016 | Science Bulletin2016，61，4： | 5 |
| 3 | EAST-Educational Adaptive-optics Solar Telescope显示文摘For the public having a better understanding of solar activities,the Educational Adaptive-optics Solar Telescope(EAST)was built in July 2021 and is located at the Shanghai Astronomy Museum.The EAST consists of a 65 cm aperture solar telescope with a 177-element adaptive optics system and two-channel high resolution imaging system at the Hαand TiO bands,in addition to three full disk solar telescopes at CaK,Hαand TiO bands equipped on the tube of the main telescope.In this paper,the configuration of the EAST is described.Its performance and on-sky observational results are presented.The EAST,to our knowledge,is the most advanced solar telescope for the popularization of science in the world.Due to its excellent performance,the data acquired by the EAST can also be used for research on solar physics and space weather prediction. | Changhui Rao Xuejun Rao Zhimao Du Hua Bao Cheng Li Jinlong Huang Youming Guo Libo Zhong Qing Lin Xin Ge Jinsheng Yang Xinlong Fan Yangyi Liu Dan Jia Xin Li Mei Li Ming Zhang Yuntao Cheng Jiahui Zhou Jiawen Yao Lanqiang Zhang Naiting Gu | 2022 | Research in Astronomy and Astrophysics2022，22，6： | 3 |
| 4 | First light of solar multi-conjugate adaptive optics at the 1-m new vacuum solar telescope显示文摘Observations play a leading role in any branches of astronomy,including solar physics.In order to solve fundamental problems,such as solar dynamo[1],coronal heating[2]and the triggering of major solar eruptions[3],solar observations with spatial resolution better than 0.1 arcsec are required.Such a goal cannot be achieved without the help of adaptive optics(AO),which eliminates the wavefront distortion caused by atmosphere turbulence[4,5].However,solar observations are performed over an extended field of | ChangHui Rao LanQiang Zhang Lin Kong YouMing Guo XueJun Rao Hua Bao Lei Zhu LiBo Zhong | 2018 | Science China(Physics,Mechanics & Astronomy)2018，61，8： | 2 |
| 5 | Ground-layer adaptive optics for the New Vacuum Solar Telescope:Instrument description and first results显示文摘Ground-layer adaptive optics(GLAO)has shown its potential for use in solar observation owing to its wide field-of-view(FOV)correction.A high-order GLAO system that consists of a multiple direction Shack-Hartmann wavefront sensor(WFS),a realtime controller with a multi-CPU processor,and a 151-element deformable mirror was developed for the 1-m New Vacuum Solar Telescope at Yunnan Observatories,Chinese Academy of Sciences.A hexagonal microlens with 9×8 subapertures is employed in the WFS.The detection FOV is 42′′×37′′,in which 9(3×3)guide regions are extracted for multiple direction wavefront sensing with a frame rate of up to 2200 Hz.To our knowledge,this is the first professional solar GLAO system used as a regularly operating instrument for scientific observations.Its installation and adjustment were performed in the summer of 2021.In this article,a detailed account of the GLAO system and its first light results and a comprehensive analysis of the performance of the GLAO system are provided.The results show that this system can effectively improve the imaging quality after compensating for the wavefront aberration due to ground-layer turbulence. | Lanqiang Zhang Hua Bao Xuejun Rao Youming Guo Libo Zhong Xian Ran Nanfei Yan Jinsheng Yang Cheng Wang Jiahui Zhou Ying Yang Yunyao Long Xinlong Fan Zhongyi Feng Donghong Chen Changhui Rao | 2023 | Science China(Physics,Mechanics & Astronomy)2023，66，6： | 1 |
| 6 | Solar adaptive optics systems for the New Vacuum Solar Telescope at the Fuxian Lake Solar Observatory显示文摘Adaptive optics(AO)is essential for high-quality ground-based observations with large telescopes because it counters the impact of wavefront aberrations caused by atmospheric turbulence.The new vacuum solar telescope(NVST)is one of the most important high-resolution solar observation instruments in the world.Three sets of solar adaptive optics systems have been developed and installed on this telescope:conventional adaptive optics,ground layer adaptive optics,and multi-conjugate adaptive optics.These have been in operation from 2018 to 2023.This paper details the development and application of solar adaptive optics on the NVST and discusses the newest instrumentation. | Lanqiang Zhang Xuejun Rao Hua Bao Youming Guo Jinsheng Yang Nanfei Yan Xian Ran Dingkang Tong Xinlong Fan Zhongyi Feng Changhui Rao | 2024 | Astronomical Techniques and Instruments2024，1，2： | 0 |
