Angular Sizes and Effective Temperatures of O-type Stars from Optical Interferometry with the CHARA Array

Gordon, Kathryn D; Gies, D. R.; Schaefer, Gail; Huber, Daniel; Ireland, Michael; Hillier, D. John

Description

We present interferometric observations of six O-type stars that were made with the Precision Astronomical Visible Observations beam combiner at the Center for High Angular Resolution Astronomy (CHARA) Array. The observations include multiple brackets for three targets, λ Ori A, ζ Oph, and 10 Lac, but there are only preliminary, single observations of the other three stars, ξ Per, α Cam, and ζ Ori A. The stellar angular diameters range from 0.55 mas for ζ Ori A down to 0.11 mas for 10 Lac, the...[Show more]
