Chemical signatures of planetary systems in their host stars. Near-infrared spectroscopy of four planet-hosting wide binaries
Dongwook Lim, Sol Yun, Andreas J. Koch-Hansen +3
An important open question in exoplanet studies is whether planets leave detectable chemical fingerprints on their host stars. While several studies have suggested possible planeta…
Substructures of the Milky Way's Retrograde Halo: Evidence for Multiple Accretion Events
Young Kwang Kim, Young Sun Lee, Timothy C. Beers
We investigate the progenitors of low-inclination retrograde substructures in the Milky Way (MW) halo, which are remnants of accreted dwarf galaxies on retrograde orbits. Our sampl…
Carbon-Enhanced Metal-Poor Star Candidates in the Milky Way from J-PLUS and S-PLUS
Jihye Hong, Timothy C. Beers, Yang Huang +4
Recent large-scale multi-band photometric surveys now enable elemental-abundance estimates for millions of stars with accuracies approaching those of low- to medium-resolution spec…
