Impact of Satellite Constellations on Observations with the 80-cm Telescope and the Mini-SiTian at the Xinglong Observatory, NAOC
Jing Ren, Zhou Fan, Hong-rui Gu +6
The rapid development of mega-constellations in low Earth orbit (LEO) severely impacts ground-based optical astronomical observations. By combining WorldWide Telescope (WWT) simula…
Artificial Satellite Trails Detection Using U-Net Deep Neural Network and Line Segment Detector Algorithm
Xiaohan Chen, Hongrui Gu, Cunshi Wang +6
With the rapid increase in the number of artificial satellites, astronomical imaging is experiencing growing interference. When these satellites reflect sunlight, they produce stre…
The Mini-SiTian Array: Imaging Processing Pipeline
Kai Xiao, Zhirui Li, Yang Huang +19
As a pathfinder of the SiTian project, the Mini-SiTian (MST) array, employed three commercial CMOS cameras, represents a next-generation, cost-effective optical time-domain survey…
Spectroscopic evidence for a large spot on the dimming Betelgeuse
Sofya Alexeeva, Gang Zhao, Dong-Yang Gao +4
During October 2019 and March 2020, the luminous red supergiant Betelgeuse demonstrated an unusually deep minimum of its brightness. It became fainter by more than one magnitude an…
Simulating Photometric Images of Moving Targets with Photon-mapping
Junju Du, Shaoming Hu, Xu Chen +2
We present a novel, easy-to-use method based on the photon-mapping technique to simulate photometric images of moving targets. Realistic images can be created in two passes: photon…
The NLTE Analyses of Carbon Emission Lines in the Atmospheres of O and B type Stars
Sofya Alexeeva, Kozo Sadakane, Masayoshi Nishimura +2
We present a model atom for C I - C II - C III - C IV using the most up-to-date atomic data and evaluated the non-local thermodynamic equilibrium (NLTE) line formation in classical…
Sky Brightness at Weihai Observatory of Shandong University
Di-Fu Guo, Shao-Ming Hu, Xu Chen +2
In this paper, a total of about 28000 images in and band obtained on 161 nights using the one-meter optical telescope at Weihai Observatory (WHO) of Shandong University sin…
The photometric system of the One-meter Telescope at Weihai Observatory of Shandong University
Shao-Ming Hu, Sheng-Hao Han, Di-Fu Guo +1
The one-meter telescope at Weihai Observatory of Shandong University is an f/8 Cassegrain telescope. Three sets of filters, including Johnson--Cousins UBVRI, Sloan Digital Sky Surv…
