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…

Spectroscopic and Interferometric Measurements of Nine K Giant Stars

Ellyn K. Baines, Michaela P. Döllinger, Eike W. Guenther +3

We present spectroscopic and interferometric measurements for a sample of nine K giant stars. These targets are of particular interest because they are slated for stellar oscillati…

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 Mass of the Planet-hosting Giant Star Beta Geminorum Determined from its p-mode Oscillation Spectrum

A. P. Hatzes, M. Zechmeister, J. Matthews +7

We use precise radial velocity measurements and photometric data to derive the frequency spacing of the p-mode oscillation spectrum of the planet-hosting star Beta Gem. This spacin…

Angular Diameters and Effective Temperatures of Twenty-five K Giant Stars from the CHARA Array

Ellyn K. Baines, Michaela P. Doellinger, Felice Cusano +10

Using Georgia State University's CHARA Array interferometer, we measured angular diameters for 25 giant stars, six of which host exoplanets. The combination of these measurements a…
