LAMOST DR10 Spectroscopic Multiple-Star Catalogs and Orbital Solutions
Yuxin Han ; Kai Li
This data resource provides catalogs of spectroscopic multiple-star systems identified from LAMOST DR10 medium-resolution spectra. It includes SB1, SB2, and ST candidates, as well as orbital solutions for a subset of SB2 systems with high-quality exposures and hierarchical triple (HT) star candidates. Radial velocities were measured by fitting cross-correlation functions using Gausspy+, and orbital parameters were derived using The Joker. Orbital solutions for short-period SB2 systems (P < 200 days) and HT candidates are provided in one table, while long-period SB2 systems (P ≥ 200 days) are presented separately.  This dataset enables studies of stellar multiplicity, binary and triple star evolution, and Galactic structure, providing a valuable resource for statistical analyses of spectroscopic multiple-star systems.
