The Galactic Bulge can uniquely be studied from large samples of individual stars and is
therefore of prime importance for understanding the stellar population structure of bulges in …

We review the application of the one-dimensional Mixing Length Theory (MLT) model of
convection in stellar interiors and low-mass stellar evolution. We summarize the history of …

We combine high-resolution spectroscopic data from APOGEE-2 survey Data Release 16
(DR16) with broad-band photometric data from several sources as well as parallaxes from …

We investigate the inner regions of the Milky Way using data from APOGEE and Gaia EDR3.
Our inner Galactic sample has more than 26 500 stars within| X Gal|< 5 kpc,| Y Gal|< 3.5 …

The compositions of stars are a critical diagnostic tool for many topics in astronomy such as
the evolution of our Galaxy, the formation of planets, and the uniqueness of the Sun …

We present the most extensive and detailed reddening maps of the Magellanic Clouds
(MCs) derived from the color properties of Red Clump (RC) stars. The analysis is based on …

We explore the chemodynamical properties of a sample of barred galaxies in the Auriga
magnetohydrodynamical cosmological zoom-in simulations, which form boxy/peanut (b/p) …

To understand the formation of the Milky Way's prominent bar it is important to know whether
stars in the bar differ in the chemical element composition of their birth material as compared …

Abstract Mapping Nearby Galaxies at Apache Point Observatory provides the opportunity to
make precise spatially resolved measurements of the IMF slope in galaxies owing to its …

The origins of the elements and isotopes of cosmic material is a critical aspect of
understanding the evolution of the universe. Nucleosynthesis typically requires physical …
