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…
The radius and effective temperature of the binary Ap star beta CrB from CHARA/FLUOR and VLT/NACO observations
H. Bruntt, P. Kervella, A. Merand +14
The prospects for using asteroseismology of rapidly oscillating Ap (roAp) stars are hampered by the large uncertainty in fundamental stellar parameters. Results in the literature f…
Interferometric Observations of Algol
T. Borkovits, Sz. Csizmadia, Zs. Paragi +6
We determined the spatial orientation of the Algol AB close pair orbital plane using optical interferometry with the CHARA Array, and radio interferometry with the European VLBI Ne…
Interferometric Observations of the Hierarchical Triple System Algol
Sz. Csizmadia, T. Borkovits, Zs. Paragi +10
Algol is a triple stellar system consisting of a close semidetached binary orbited by a third object. Due to the disputed spatial orientation of the close pair, the third body pert…
Asteroseismology and interferometry of the red giant star epsilon Oph
A. Mazumdar, A. Merand, P. Demarque +16
The GIII red giant star epsilon Oph has been found to exhibit several modes of oscillation by the MOST mission. We interpret the observed frequencies of oscillation in terms of the…
Eleven Exoplanet Host Star Angular Diameters from the CHARA Array
Ellyn K. Baines, Harold A. McAlister, Theo A. ten Brummelaar +4
We directly measured the angular diameters for 11 exoplanet host stars using Georgia State University's CHARA Array interferometer and calculated their linear radii and effective t…
