A Planetary Nebula from a 5.7 Progenitor in a 90 Myr M31 Star Cluster
Pinjian Chen, Bingqiu Chen, Xiaodian Chen +2
Planetary nebulae (PNe) trace the late evolution of low-to-intermediate-mass stars, yet the masses of their progenitors are rarely measured directly. Here we present a PN physicall…
Homogeneous Stellar Atmospheric Parameters and 22 Elemental Abundances for FGK Stars Derived From LAMOST Low-resolution Spectra with DD-Payne

Context. The Javalambre Photometric Local Universe Survey (J-PLUS) has obtained precise photometry in twelve specially designed filters for large numbers of Galactic stars. Derivin…
Stellar Loci V: Photometric Metallicities of 27 Million FGK Stars based on Gaia Early Data Release 3
Shuai Xu, Haibo Yuan, Zexi Niu +3
We combine LAMOST DR7 spectroscopic data and Gaia EDR3 photometric data to construct high-quality giant (0.7 1.4) and dwarf (0.5 1.5) samples in the hi…
