VizieR Online Data Catalog: Abundance catalogue of solar twins in GALAH (Walsen+, 2024)
Abstract
Stellar parameter and chemical abundance data for 38320 solar twin stars. The data was produced by using The Cannon (Ness et al., 2015ApJ...808...16N, cat. J/ApJ/808/16) with GALAH DR3 solar twin data (Buder et al., 2021MNRAS.506..150B, Cat. J/MNRAS/506/150). The model was trained using 150 high SNR spectra and applied over the whole solar twin catalogue, reporting new values and internal uncertainties for these labels (for more information, see paper). We report the values and internal uncertainties for following stellar parameters: effective temperature 'teff', surface gravity 'log g' and metallicity '[Fe/H]'. We also report the values and internal uncertainties for 14 chemical abundances: [Na/Fe], [Mg/Fe], [Al/Fe], [Si/Fe], [Ca/Fe], [Sc/Fe], [Ti/Fe], [Cr/Fe], [Mn/Fe], [Ni/Fe], [Cu/Fe], [Zn/Fe], [Y/Fe], [Ba/Fe].
