The Initial mass function of field stars with mass 1 varies with metallicity
Dan Qiu, Chao Liu, Jennifer A. Johnson +2
We investigated a volume-limited sample of LAMOST main-sequence stars with masses from 0.25 to 1 and distances of 150-350 pc to explore how the stellar initial mass fun…
Stellar initial mass function in the 100-pc solar neighbourhood
Yu-Ting Wang, Chao Liu, Jiadong Li
The stellar initial mass function (IMF) is among the most fundamental distributions in astrophysics, defined as the mass spectrum of stars produced in a single star-formation event…
Identification of 30,000 White Dwarf-Main Sequence binaries candidates from Gaia DR3 BP/RP(XP) low-resolution spectra
Jiadong Li, Yuan-Sen Ting, Hans-Walter Rix +5
White dwarf-main sequence (WDMS) binary systems are essential probes for understanding binary stellar evolution and play a pivotal role in constraining theoretical models of variou…
TYC 3340-2437-1: A Quadruple System with A Massive Star
Jiao Li, Chao Liu, Changqing Luo +10
Hierarchical massive quadruple systems are ideal laboratories for examining the theories of star formation, dynamical evolution, and stellar evolution. The successive mergers of hi…
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…
The Distribution of Semi-Detached Binaries. I.An Efficient Pipeline
JianPing Xiong, Xu Ding, Jiadong Li +5
Semi-detached binaries are in the stage of mass transfer and play a crucial role in studying mass transfer physics between interacting binaries. Large-scale time-domain surveys pro…
Stellar Initial Mass Function Varies with Metallicities and Time
Jiadong Li, Chao Liu, Zhi-Yu Zhang +4
Most structural and evolutionary properties of galaxies strongly rely on the stellar initial mass function (IMF), namely the distribution of the stellar mass formed in each episode…
The Eclipsing Binaries from the LAMOST Medium-resolution Survey.III. A High-precision Empirical Stellar Mass Library
Jianping Xiong, Chao Liu, Jiao Li +6
High-precision stellar mass and radius measured directly from binaries can effectively calibrate the stellar models. However, such a database containing full spectral types and lar…
Double-, triple-line spectroscopic candidates in the LAMOST Medium-Resolution Spectroscopic Survey
Chun-qian Li, Jian-rong Shi, Hong-liang Yan +3
The LAMOST Medium-Resolution Spectroscopic Survey (LAMOST-MRS) provides an unprecedented opportunity for detecting multi-line spectroscopic systems. Based on the method of Cross-Co…
Stellar parametrization of LAMOST M dwarf stars
Jiadong Li, Chao Liu, Bo Zhang +3
M dwarf stars are the most common stars in the Galaxy, dominating the population of the Galaxy by numbers at faint magnitudes. Precise and accurate stellar parameters for M dwarfs…
