Stellar atmospheric parameters and 22 elemental abundances from LAMOST spectra with DD-Payne
Mengzhang ; Maosheng Xiang
Value-added catalogs of stellar atmospheric parameters and elemental abundance ratios for 6439,359 stars ( 9245,463 spectra) derived from LAMOST DR9 low-resolution spectra using DD-Payne. The catalog content includes basic atmospheric parameters (Teff, logg, [Fe/H], Vmic) and abundance ratio ([X/Fe]) of 13 elements, namely C, N, O, Na, Mg, Al, Si, Ca, Ti, Cr, Mn, Ni, Ba, for all these stars. Additionally, the abundance ratios of Sr, Y, Zr, La, Ce, Nd, Sm, and Eu are provided for about 3.6 million stars with SNR higher than 20. There are two separate tables in .FITS format. One is for recommended values of all labels. For O, Na, Mg, Al, Si, Ca, Ti, Cr, Mn, Ni, Sr, Y, Zr, Ba, La, Ce, Nd, Sm, and Eu, the abundances in the recommended catalog are calibrated. The original abundances of these elements before calibrations are provided in the other catalog. More detailed information of these catalogs can be found in the paper via the link https://doi.org/10.3847/1538-4365/add016. This new version is similar to previous one, but it includes the measurements of more M-giants.
