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…
Near-Infrared Spectroscopy with IGRINS-2 for Studying Multiple Stellar Populations in Globular Clusters
Dongwook Lim, Young-Wook Lee, Sol Yun +53
Recent advancements in near-infrared (NIR) spectroscopy have opened new opportunities for studying multiple stellar populations in globular clusters (GCs), particularly for newly d…
Two stellar populations with different metallicities in the low-mass globular cluster Gran 5
Dongwook Lim, Sang-Hyun Chun, Young-Wook Lee +3
Context. With the increasing number of discoveries of globular clusters in the inner Milky Way, the need for spectroscopic confirmation and further investigation of their stellar p…
Is the RSGC4 (Alicante 8) cluster a real star cluster?: Peculiar radial velocities of red supergiant stars
Sang-Hyun Chun, GyuChul Myeong, Jae-Joon Lee +1
Young massive star clusters, like the six red supergiant clusters in the Scutum complex, provide valuable insights into star-formation and galaxy structures. We investigated the hi…
Chemical homogeneity of wide binary system: An approach from Near-Infrared spectroscopy
Dongwook Lim, Andreas J. Koch-Hansen, Seungsoo Hong +2
Wide binaries, with separations between two stars from a few AU to more than several thousand AU, are valuable objects for various research topics in Galactic astronomy. As the num…
