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…
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…
