A Search for Exoplanets around Northern Circumpolar Stars. IV. Six Planet Candidates to the K Giants, HD 44385, HD 97619, HD 106574, HD 118904, HD 164428, and HD 202432

Gwanghui Jeong, Inwoo Han, Myeong-Gu Park +5

We report the discovery of long-period radial velocity (RV) variations in six intermediate-mass K-giant stars using precise RV measurements. These discoveries are part of the Searc…

Photospheric carbon, nitrogen, and oxygen abundances of A-type main-sequence stars

Yoichi Takeda, Satoshi Kawanomoto, Naoko Ohishi +4

Based on the spectrum fitting method applied to CI 5380, NI 7486, and OI 6156-8 lines, we determined the abundances of C, N, and O for 100 mostly A-type main-sequence stars (late B…

Search for exoplanets around northern circumpolar stars III. long-period radial velocity variations in hd 18438 and hd 158996

Tae-Yang Bang, Byeong-Cheol Lee, Gwang-Hui Jeong +2

Detecting exoplanets around giant stars sheds light on the later-stage evolution of planetary systems. We observed the M giant HD 18438 and the K giant HD 158996 as part of a Searc…

The Radial Velocity Variability of the K-giant Gamma Draconis: Stellar Variability Masquerading as a Planet

A. P. Hatzes, M. Endl, W. D. Cochran +9

We present precise stellar radial velocity measurements of Gamma Dra taken from 2003 to 2017. The data from 2003 to 2011 show coherent, long-lived variations with a period of 702 d…
