A Morpho-Kinematic Study of the Enigmatic Emission Nebula NGC 6164/5 Surrounding the Magnetic O-type Star HD 148937
Beomdu Lim, Yael Naze, Seok-Jun Chang +1
HD 148937 is a peculiar massive star (Of?p) with a strong magnetic field (1kG). The hourglass-shaped emission nebula NGC 6164/5 surrounds this star. This nebula is presumed to orig…
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.…
The kinematics of young stellar population in the W5 region of the Cassiopeia OB6 association: implication on the formation process of stellar associations
Beomdu Lim, Jongsuk Hong, Jinhee Lee +3
The star-forming region W5 is a major part of the Cassiopeia OB6 association. Its internal structure and kinematics may provide hints of the star formation process in this region.…
A deep optical survey of young stars in the Carina Nebula. I. -- UBVRI photometric data and fundamental parameters
Hyeonoh Hur, Beomdu Lim, Moo-Young Chun
We present the deep homogeneous photometric data of 135,071 stars down to mag and I ~ 22 mag toward the Carina Nebula. These stars are cross-matched with those fr…
