A Search for Exoplanets around Northern Circumpolar Stars X. The origin of radial velocity variations in the evolved star HD 216595

Sang-Hee Kim, Byeong-Cheol Lee, Shenghong Gu +9

Detecting planetary companions around evolved stars, particularly asymptotic giant branch (AGB) stars, is challenging due to intrinsic stellar variability such as surface convectio…

Initial Mass Functions of Young Stellar Clusters from the Gemini Spectroscopic Survey of Nearby Galaxies. II. Young Clusters in NGC 1313

Jae-Rim Koo, Hyun-Jeong Kim, Beomdu Lim

We present a spectroscopic study of young stellar clusters in the barred spiral galaxy NGC 1313. Integrated light spectra of 11 clusters, obtained using the GMOS-S instrument on th…

Formation process of young stellar population in Messier 16 from a kinematic perspective

Beomdu Lim, Hyeong-Sik Yun, Hyun-Jeong Kim +4

We present a kinematic study of young stars in Messier 16 (M16) using the Gaia Data Release 3 and high-resolution spectra. A total of 345 stars are selected as genuine members usin…

Initial Mass Functions of Young Stellar Clusters from the Gemini Spectroscopic Survey of Nearby Galaxies I. Young Massive Clusters in the Antennae galaxies

Jae-Rim Koo, Hyun-Jeong Kim, Beomdu Lim

The stellar initial mass function (IMF) is a key parameter to understand the star formation process and the integrated properties of stellar populations in remote galaxies. We pres…

SPECtrophotometer for TRansmission spectroscopy of exoplanets (SPECTR)

Yeon-Ho Choi, Myeong-Gu Park, Kang-Min Kim +9

The SPECtrophotometer for TRansmission spectroscopy of exoplanets (SPECTR) is a new low-resolution optical (3800 Ã - 6850 Ã ) spectrophotometer installed at the Bohyunsan Optical A…
