Mass, Luminosity, and Stellar Age of Early-type Stars from the LAMOST Survey
Published 2025-01-01“…Typically, effective temperature ( T _eff ), surface gravity ( $\mathrm{log}\ g$ ), and metallicity ([M/H]) are derived from stellar spectra, then M , L , and stellar age ( t ) can be obtained by interpolating in the grid of stellar evolutionary models. In this paper, we use random forest in combination with the evolutionary grid from PARSEC 1.2S to determine M , L , t , and initial mass ( M _i ) for early-type main-sequence stars ( T _eff ≥ 7000 K) as identified from the LAMOST survey. …”
