Description
We present the APOGEE-2 star forming regions catalog (Román-Zúñiga et al 2023) which is based on spectral labels (Teff, Logg, [Fe/H] from the APOGEE Net II neural network (Sprague et al 2022). We present preliminary follow-up work on the relation between young star and gas kinematics in 3 regions (Rosette, Cygnus-X, Vela Ridge). We also present preliminary results on applying the APOGEE spectral parameter fitting and interpolating code TONALLI (L. Adame et al. 2023), which provides spectral parameters based on the MARCS grid, with accurate confidence level calculations (Román-Zúñiga et al. in prep), and compare with those of APOGEE Net. We are currently studying the effects of circumstellar disk emission on parameter determination (C. Zepeda, master thesis project, UNAM) and investigate line parameters for accretion related features in BOSS counterparts using the Line Forest catalog. The main goal is to get closer to answer the question ""How far we are from providing spectral parameters for pre-main sequence stars with comparable reliability to main-sequence and evolved populations, given the fact that young stars have accretion in play?
