Half a Million M Dwarf Stars Characterized Using Domain-Adapted Spectral Analysis
Shuo Zhang, Hua-Wei Zhang, Yuan-Sen Ting +5
We present fundamental atmospheric parameters (Teff and log g) and metallicities ([M/H]) for 507,513 M dwarf stars using low-resolution spectra (R~1800) from LAMOST DR10. By employ…
