A robust method for identifying Be stars in the LAMOST Data Release 11 based on Deep-learning approach
Lei Tan, Hui Deng, Ying Mei +4
Be stars are rapidly rotating B-type stars that exhibit Balmer emission lines in their optical spectra. These stars play an important role in studies of stellar evolution and disk…
Quasi-periodic Variations of Coronal Mass Ejections with Different Angular Widths
Xia Li, Hui Deng, Feng Wang +2
Coronal mass ejections (CMEs) are energetic expulsions of organized magnetic features from the Sun. The study of CME quasi-periodicity helps establish a possible relationship betwe…
The Temporal and Spatial Behaviors of CME Occurrence Rate at Different Latitudes
Jiaqi Lin, Feng Wang, Linhua Deng +3
The statistical study of the Coronal Mass Ejections (CMEs) is a hot topic in solar physics. To further reveal the temporal and spatial behaviors of the CMEs at different latitudes…
A Robust Hot Subdwarfs Identification Method Based on Deep Learning
Lei Tan, Ying Mei, Zhicun Liu +5
Hot subdwarf star is a particular type of star that is crucial for studying binary evolution and atmospheric diffusion processes. In recent years, identifying Hot subdwarfs by mach…
A Catalog of LAMOST Variable Sources Based on Time-domain Photometry of ZTF
Tingting Xu, Chao Liu, Feng Wang +4
The identification and analysis of different variable sources is a hot issue in astrophysical research. The Large Sky Area Multi-Object Fiber Spectroscopic Telescope (LAMOST) spect…
The spatial distribution of quasi-biennial oscillations in the high-latitude solar activity
L. H. Deng, Y. Fei, H. Deng +2
Quasi-biennial oscillations (QBOs) are considered as a fundamental mode of solar magnetic activity at low latitudes (). However, the evolutionary aspect and the hemis…
Systematic Regularity of Solar Coronal Rotation During the Time Interval 1939-2019
L. H. Deng, X. J. Zhang, H. Deng +2
Temporal variation of the solar coronal rotation appears to be very complex and its relevances to the eleven-year solar activity cycle are still unclear. Using the modified coronal…
Periodic variation and phase analysis of grouped solar flare with sunspot activity
Hui Deng, Ying Mei, Feng Wang
Studies on the periodic variation and the phase relationship between different solar activity indicators are useful for understanding the long-term evolution of solar activity cycl…
On Midrange Periodicities in Solar Radio Flux and Sunspot Areas
Ying Mei, Hui Deng, Feng Wang
Using the Hilbert-Huang transform technique, we investigate the midrange periodicities in solar radio flux at 2800 MHz (F10.7) and sunspot areas (SAs) from February 1, 1947 to Sept…
