The Stellar "Snake"-V: the census within 3 kpc in the Solar Neighborhood
Xiang-Ming Yang, Ju-Yong Zhang, Hai-Jun Tian
We present a Gaia DR3 source-level census of \emph{Stellar Snake} complexes within 3\,kpc of the Sun. We define a Stellar Snake as a mutually coherent association of two or more st…
Design and Implementation of a Scalable Correlator Based on ROACH2+GPU Cluster for Tianlai 96-Dual-Polarization Antenna Array
Zhao Wang, Ji-Xia Li, Ke Zhang +7
The digital correlator is one of the most crucial data processing components of a radio telescope array. With the scale of radio interferometeric array growing, many efforts have b…
The Stellar "Snake" -- II: The Mass Function
Xiang-Ming Yang, Sarah A. Bird, Jiadong Li +8
We present a comprehensive investigation on the mass function (MF) of a snake-like stellar structure in the solar neighbourhood, building on our previous discovery. To ensure the r…
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…
