3.5-meter Segmented-Mirror Robotic Space Telescope Mission White Paper V. Key Scientific Mission: Compact-Object Time-Domain Science
Juhan Kim, Yong-Woo Kang, Sang Hyun Lee +22
An isolated compact object retains the point-source resolving power of the space-based slitless spectrograph. The baseline wavelength range is 0.2--1.5 m. The planning baseline…
3.5-meter Segmented-Mirror Robotic Space Telescope Mission White Paper IV. Key Scientific Mission: Solar-System Small Bodies and Planetary Defense
Juhan Kim, Yong-Woo Kang, Sang Hyun Lee +22
The baseline 0.2--1.5 m observatory provides rapid-response astrometry, visible and near-infrared taxonomy, rotation and phase curves, recovery, and long-arc orbit improvement f…
3.5-meter Segmented-Mirror Robotic Space Telescope Mission White Paper III. Key Scientific Mission: Exoplanet Science with a Coronagraph
Juhan Kim, Sang Hyun Lee, Yong-Woo Kang +22
This volume defines the exoplanet science program enabled by the dedicated high-contrast coronagraph in the baseline science payload of the 3.5-meter Segmented-Mirror Robotic Space…
Origin of the Long-Period Radial Velocity Variation in the Red Supergiant HD 216946 (V424 Lac)
Byeong-Cheol Lee, Myeong-Gu Park
We present precise radial-velocity (RV) observations of the K-type red supergiant HD~216946 (V424 Lac) obtained over approximately 22 years with the Bohyunsan Optical Astronomy Obs…
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…
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 Å - 6850 Å) spectrophotometer installed at the Bohyunsan Optical As…
Low-amplitude and long-period radial velocity variations in giants HD 3574, 63 Cygni, and HD 216946 (Research Note)
B. -C. Lee, I. Han, M. -G. Park +2
Aims. We study the low-amplitude and long-period variations in evolved stars using precise radial velocity measurements. Methods. The high-resolution, fiber-fed Bohyunsan Observato…
Detection of an exoplanet around the evolved K giant HD 66141
B. -C. Lee, D. E. Mkrtichian, I. Han +2
Aims. We have been carrying out a precise radial velocity (RV) survey for K giants to search for and study the origin of the lowamplitude and long-periodic RV variations. Methods.…
Planetary companions orbiting M giants HD 208527 and HD 220074
B. -C. Lee, I. Han, M. -G. Park
Aims. The purpose of the present study is to research the origin of planetary companions by using a precise radial velocity (RV) survey. Methods. The high-resolution spectroscopy o…
