We discuss the use of the spectral range near 7570 Å to determine the Mg isotopic ratios in carbon stars using the B'2 Sigma +-X 2 Sigma + system of the MgH...

We explore the relationships between the chemistry, ages, and locations of stars in the Galaxy using asteroseismic data from the K2 mission and spectroscopic...

The spectral analysis and data products in Data Release 16 (DR16; 2019 December) from the high-resolution near-infrared Apache Point Observatory Galactic...

Elements with weak and blended spectral features in stellar spectra are challenging to measure and require specialized analysis methods to precisely measure...

We present Cu and Zn abundances for a sample of 30 stars spanning a metallicity range between solar and [Fe/H]=-3. LTE abundances were obtained using Kurucz...

Individual chemical abundances for 14 elements (C, O, Na, Mg, Al, Si, K, Ca, Ti, V, Cr, Mn, Fe, and Ni) are derived for a sample of M dwarfs using high...

The recently discovered phosphorus-rich stars pose a challenge to stellar evolution and nucleosynthesis theory, as none of the existing models can explain their...

Since the discovery of chemically peculiar stars in globular clusters in the last century, the study of multiple populations has become increasingly important...

The DESI Milky Way Survey (MWS) will observe ≥8 million stars between 16 < r < 19 mag, supplemented by observations of brighter targets under poor observing...
