A White Dwarf-Main Sequence Binary Unveiled by Time-Domain Observations from LAMOST and TESS
Ling-Lin Zheng, Wei-Min Gu, Mouyuan Sun +16
We report a single-lined white dwarf-main sequence binary system, LAMOST J172900.17+652952.8, which is discovered by LAMOST's medium resolution time-domain surveys. The radial velo…
ET White Paper: To Find the First Earth 2.0
Jian Ge, Hui Zhang, Weicheng Zang +163
We propose to develop a wide-field and ultra-high-precision photometric survey mission, temporarily named "Earth 2.0 (ET)". This mission is designed to measure, for the first time,…
K2 photometry on oscillation mode variability: the new pulsating hot B subdwarf star EPIC 220422705
Xiao-Yu Ma, Weikai Zong, Jian-Ning Fu +4
We present an analysis of oscillation mode variability in the hot B subdwarf star EPIC~220422705, a new pulsator discovered from ~days of {\em K}2 photometry. The high-qual…
Characterization of Kepler targets based on medium-resolution LAMOST spectra analyzed with ROTFIT
A. Frasca, J. Molenda-Zakowicz, J. Alonso-Santiago +7
In this work we present the results of our analysis of 16,300 medium-resolution LAMOST spectra of late-type stars in the Kepler field with the aim of determining the stellar parame…
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
The Large Sky Area Multi-Object Fiber Spectroscopic Telescope (LAMOST), also known as the Guoshoujing Telescope, is a major national scientific facility for astronomical research l…
Detecting and Monitoring Tidal Dissipation of Hot Jupiters in the Era of SiTian
Fan Yang, Wei Wang, Xing Wei +13
Transit Timing Variation (TTV) of hot Jupiters provides direct observational evidence of planet tidal dissipation. Detecting tidal dissipation through TTV needs high precision tran…
The Properties and Evolutions of Starspots on Three Detached Eclipsing Binaries in the LAMOST-Kepler survey
Jiaxin Wang, Jianning Fu, Weikai Zong +4
The spotted detached eclipsing binary (DEB) offers insights into starspots on the binary. Three spotted DEBs, KIC 8097825, KIC 6859813, and KIC 5527172, which were observed by the…
