chromospheric activity of F-, G-, and K-type stars observed by the LAMOST Medium-Resolution Spectroscopic Survey
Han He, Weitao Zhang, Haotong Zhang +3
The distribution of stellar chromospheric activity with respect to stellar atmospheric parameters (effective temperature , surface gravity ,…
The Stellar Abundances and Galactic Evolution Survey (SAGES) -- -- I. General Description and the First Data Release (DR1)
Zhou Fan, Gang Zhao, Wei Wang +35
The Stellar Abundances and Galactic Evolution Survey (SAGES) of the northern sky is a specifically-designed multi-band photometric survey aiming to provide reliable stellar paramet…
Deep Learning Applications Based on WISE Infrared Data: Classification of Stars, Galaxies and Quasars
Guiyu Zhao, Bo Qiu, A-Li Luo +4
The Wide-field Infrared Survey Explorer (WISE) has detected hundreds of millions of sources over the entire sky. However, classifying them reliably is a great challenge due to dege…
An in-depth exploration of LAMOST Unknown spectra based on density clustering
Haifeng Yang, Xiaona Yin, Jianghui Cai +6
LAMOST (Large Sky Area Multi-Object Fiber Spectroscopic Telescope) has completed the observation of nearly 20 million celestial objects, including a class of spectra labeled `Unkno…
Galaxy Image Classification using Hierarchical Data Learning with Weighted Sampling and Label Smoothing
Xiaohua Ma, Xiangru Li, Ali Luo +2
With the development of a series of Galaxy sky surveys in recent years, the observations increased rapidly, which makes the research of machine learning methods for galaxy image re…
Stellar Chromospheric Activity Database of Solar-like Stars Based on the LAMOST Low-Resolution Spectroscopic Survey
Weitao Zhang, Jun Zhang, Han He +3
$\require{mediawiki-texvc}$A stellar chromospheric activity database of solar-like stars is constructed based on the Large Sky Area Multi-Object Fiber Spectroscopic Telescope (LAMO…
Probable Dormant Neutron Star in a Short-Period Binary System
Tsevi Mazeh, Simchon Faigler, Dolev Bashi +24
We have identified 2XMM J125556.57+565846.4, at a distance of 600 pc, as a binary system consisting of a normal star and a probable dormant neutron star. Optical spectra exhibit a…
Planets Across Space and Time (PAST). III. Morphology of the Planetary Radius Valley as a Function of Stellar Age and Metallicity in the Galactic Context Revealed by the LAMOST-Gaia-Kepler Sample
Di-Chang Chen, Ji Wei Xie, Ji-Lin. Zhou +7
The radius valley, a dip in the radius distribution of exoplanets at ~1.9 Earth radii separates compact rocky Super-Earths and Sub-Neptunes with lower density. Various hypotheses h…
Overview of the LAMOST survey in the first decade
Hongliang Yan, Haining Li, Song Wang +24
