Detection of Gravitational Anomaly at Low Acceleration from a Highest-quality Sample of 36 Wide Binaries with Accurate 3D Velocities
K. -H. Chae, B. -C. Lee, X. Hernandez +4
We set out to accurately measure gravity in the low-acceleration range from 3D motions of isolated wide binary stars. Gaia DR3 provides…
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…
Detection of planet candidates around K giants, HD 40956, HD 111591, and HD 113996
Gwanghui Jeong, Byeong-Cheol Lee, Inwoo Han +6
Aims. The purpose of this paper is to detect and investigate the nature of long-term radial velocity (RV) variations of K-type giants and to confirm planetary companions around the…
Search for exoplanet around northern circumpolar stars - Four planets around HD 11755, HD 12648, HD 24064, and 8 Ursae Minoris
B. -C. Lee, M. -G. Park, S. -M. Lee +7
Aims. This program originated as the north pole region extension of the established exoplanet survey using 1.8 m telescope at Bohyunsan Optical Astronomy Observatory (BOAO). The ai…
Long-lived, long-period radial velocity variations in Aldebaran: A planetary companion and stellar activity
A. P. Hatzes, W. D. Cochran, M. Endl +14
We investigate the nature of the long-period radial velocity variations in Alpha Tau first reported over 20 years ago. We analyzed precise stellar radial velocity measurements for…
The TAOS Project Stellar Variability I. Detection of Low-Amplitude delta Scuti Stars
D. -W. Kim, P. Protopapas, C. Alcock +22
We analyzed data accumulated during 2005 and 2006 by the Taiwan-American Occultation Survey (TAOS) in order to detect short-period variable stars (periods of <~ 1 hour) such as del…
