MK-like spectral classification
Listed in IVOA Registry (Virtual Observatory)
An MK-like spectral classification has been conducted for 1224 hot subdwarf stars with LAMOST DR9 low-resolution spectra.
Description
The whole sample was divided into four categories according to the spectral line characteristics: He-normal, He-weak, He-strong C, and He-strong. Each selected spectrum was assigned a spectral class, a luminosity class, and a helium class by comparing the line depth and width with standard spectra selected in LAMOST.
Relationships between atmospheric parameters and spectral classification are also presented.
