TL;DR: In this article, the angular diameters of 23 nearby main-sequence stars, ranging from spectral types A7 to K0, were derived using Hipparcos parallaxes and measured bolometric fluxes.

Multiplicity of Galactic Cepheids from long-baseline interferometry I. CHARA/MIRC detection of the companion of V1334 Cygni
Alexandre Gallenne,John D. Monnier,Antoine Mérand,Pierre Kervella,Stefan Kraus,Gail H. Schaefer,Wolfgang Gieren,Grzegorz Pietrzyński,Grzegorz Pietrzyński,Laszlo Szabados,Xiao Che,Fabien Baron,Ettore Pedretti,Harold A. McAlister,T. ten Brummelaar,Judit Sturmann,Laszlo Sturmann,Nils H. Turner,Chris Farrington,Norm Vargas +19 more
TL;DR: In this article, a Cepheid companion was detected using long-baseline interferometry at visible and infrared wavelengths, and the fundamental parameters of these systems were derived based on the resulting visual orbit and radial velocities, particularly the masses of the components and the geometric distance.
