    Chemical Cartography with APOGEE: Multi-element Abundance Ratios
    We map the trends of elemental abundance ratios across the Galactic disk, spanning R=3{--}15 {kpc} and midplane distance | Z| =0{--}2 {kpc}, for 15 elements in...

    Chemical Composition of Two Bright, Extremely Metal-poor Stars from the SDSS MARVELS Pre-survey
    SDSS J082625.70+612515.10 (V = 11.4 [Fe/H] = ‑3.1) and SDSS J134144.60+474128.90 (V = 12.4 [Fe/H] = ‑3.2) were observed with the SDSS 2.5m telescope as part of...

    Chemical Evolution and the Galactic Habitable Zone of M31
    We have computed the Galactic Habitable Zones (GHZs) of the Andromeda galaxy (M31) based on the probability of terrestrial planet formation, which depends on...

    Chemical tagging with APOGEE: discovery of a large population of N-rich stars in the inner Galaxy
    Formation of globular clusters (GCs), the Galactic bulge, or galaxy bulges in general is an important unsolved problem in Galactic astronomy. Homogeneous...

    Chemical Thermodynamics Applied to the Diels–AlderReaction of C60 Fullerene with Polyacenes
    The Diels–Alder addition reactions of a series of acenes (anthracene, 9,10-dimenthylanthracene, tetracene and pentacene) to C60 fullerene are next to...
