3.5-meter Segmented-Mirror Robotic Space Telescope Mission White Paper I. Overall Architecture and Scientific Mission
Yong-Woo Kang, Sang Hyun Lee, Juhan Kim +22
We present the preliminary science concept and mission architecture of a 3.5-meter segmented-mirror robotic space telescope currently under study. The observatory is conceived as a…
3.5-meter Segmented-Mirror Robotic Space Telescope Mission White Paper II. Key Scientific Mission: Wide-Field Cosmology and Galaxy Evolution
Juhan Kim, Yong-Woo Kang, Sang Hyun Lee +22
The 3.5-meter Segmented-Mirror Robotic Space Telescope uses an image slicer for all spectroscopic observations. The planning baseline uses for the wide survey and r…
A Search for exoplanets around northern circumpolar stars VIII. filter out a planet cycle from the multi-period radial velocity variations in M giant HD 3638
Byeong-Cheol Lee, Gwanghui Jeong, Jae-Rim Koo +6
This paper is written as a follow-up observations to reinterpret the radial velocity (RV) of HD 36384, where the existence of planetary systems is known to be ambiguous. In giants,…
Long-period radial velocity variations of nine M red giants: The detection of sub-stellar companions around HD 6860 and HD 112300
Byeong-Cheol Lee, Hee-Jin Do, Myeong-Gu Park +7
Context. Certain periodic variations of radial velocities (RV) of wobbling giants originate from exoplanets. Indeed, a number of exoplanets have been discovered around giant stars.…
A search for exoplanets around north circumpolar stars. VII. Detection of planetary companion orbiting the largest host star HD 18438
Byeong-Cheol Lee, Jae-Rim Koo, Gwanghui Jeong +3
We have been conducting a exoplanet search survey using Bohyunsan Observatory Echelle Spectrograph (BOES) for the last 18 years. We present the detection of exoplanet candidate in…
Properties of Fast and Slow Bars Classified by Epicyclic Frequency Curves from Photometry of Barred Galaxies
Yun Hee Lee, Myeong-Gu Park, Ho Seong Hwang +3
We test the idea that bar pattern speeds decrease with time owing to angular momentum exchange with a dark matter halo. If this process actually occurs, then the locations of the c…
