Calibration of metallicity of LAMOST M dwarf stars Using FGK+M wide binaries
Dan Qiu, Jiadong Li, Bo Zhang +3
Estimating precise metallicity of M dwarfs is a well-known difficult problem due to their complex spectra. In this work, we empirically calibrate the metallicity using wide binarie…
Potential Impact of the Sagittarius Dwarf Galaxy on the Formation of Young O-rich Stars
Tiancheng Sun, Shaolan Bi, Xunzhou Chen +11
The Milky Way underwent significant transformations in its early history, characterised by violent mergers and satellite galaxy accretion. However, recent observations reveal notab…
Planets Across Space and Time (PAST). V. The evolution of hot Jupiters revealed by the age distribution of their host stars
Di-Chang Chen, Ji-Wei Xie, Ji-Lin Zhou +11
The unexpected discovery of hot Jupiters challenged the classical theory of planet formation inspired by our solar system. Until now, the origin and evolution of hot Jupiters are s…
Planets Across Space and Time (PAST) IV: The Occurrence and Architecture of Kepler Planetary Systems as a Function of Kinematic Age Revealed by the LAMOST-Gaia-Kepler Sample
Jia-Yi Yang, Di-Chang Chen, Ji-Wei Xie +7
One of the fundamental questions in astronomy is how planetary systems form and evolve. Measuring the planetary occurrence and architecture as a function of time directly addresses…
Measuring the Milky Way Vertical Potential with the Phase Snail in a Model Independent Way
Rui Guo, Zhao-Yu Li, Juntai Shen +2
The vertical phase-space spiral (snail) is a direct sign of dis-equilibrium of Milky Way's disc. Nevertheless, the wrapping of the phase snail contains information of the vertical…
PSF-based Analysis for Detecting Unresolved Wide Binaries
You Wu, Jiao Li, Chao Liu +5
Wide binaries play a crucial role in analyzing the birth environment of stars and the dynamical evolution of clusters. When wide binaries are located at greater distances, their co…
