The CHARA Array interferometric program on the multiplicity of classical Be stars: new detections and orbits of stripped subdwarf companions
Robert Klement, Thomas Rivinius, Douglas R. Gies +8
Rapid rotation and nonradial pulsations enable Be stars to build decretion disks, where the characteristic line emission forms. A major but unconstrained fraction of Be stars owe t…
Orbits and Dynamical Masses for the Active Hyades Multiple System HD 284163
Guillermo Torres, Gail H. Schaefer, Robert P. Stefanik +16
We report near-infrared long-baseline interferometric observations of the Hyades multiple system HD 284163, made with the CHARA array, as well as almost 43 yr of high-resolution sp…
Refining the Stellar Parameters of Ceti: a Pole-on Solar Analog
Maria Korolik, Rachael M. Roettenbacher, Debra A. Fischer +16
To accurately characterize the planets a star may be hosting, stellar parameters must first be well-determined. Ceti is a nearby solar analog and often a target for exoplanet s…
The Great Dimming of the hypergiant star RW Cephei: CHARA Array images and spectral analysis
N. Anugu, F. Baron, D. R. Gies +15
The cool hypergiant star RW Cephei is currently in a deep photometric minimum that began several years ago. This event bears a strong similarity to the Great Dimming of the red sup…
Reconstructing the mid-infrared environment in the stellar merger remnant V838 Monocerotis
Muhammad Zain Mobeen, Tomasz Kamiński, Alexis Matter +15
V838 Mon is a stellar merger remnant that erupted in 2002 in a luminous red novae event. Although it is well studied in the optical, near infrared and submillimeter regimes, its st…
Imaging the warped dusty disk wind environment of SU Aurigae with MIRC-X
Aaron Labdon, Stefan Kraus, Claire L. Davies +12
SU Aurigae is a widely studied T Tauri star and here we present original state-of-the-art interferometric observations with better uv and baseline coverage than previous studies. W…
Three-dimensional orbit of AC Her determined: Binary-induced truncation cannot explain the large cavity in this post-AGB transition disk
Narsireddy Anugu, Jacques Kluska, Tyler Gardner +17
Some evolved binaries, namely post-asymptotic giant branch binaries, are surrounded by stable and massive circumbinary disks similar to protoplanetary disks found around young star…
Precise Age for the Binary Star System 12 Com in the Coma Berenices Cluster
Rex Lam, Eric L. Sandquist, Gail H. Schaefer +11
We present measurements of the interferometrically-resolved binary star system 12 Com and the single giant star 31 Com in the cluster Coma Berenices. 12 Com is a double-lined spect…
Imaging the inner astronomical unit of Herbig Be star HD 190073
Nour Ibrahim, John D. Monnier, Stefan Kraus +13
Inner regions of protoplanetary disks host many complex physical processes such as star-disk interactions, magnetic fields, planet formation, and the migration of new planets. To d…
Multiplicity of northern bright O-type stars with optical long baseline interferometry
Cyprien Lanthermann, Jean-Baptiste Le Bouquin, Hugues Sana +16
The study of the multiplicity of massive stars gives hints on their formation processes and their evolutionary paths, which are still not fully understood. Large separation binarie…
