Multiplicity of Galactic Cepheids from long-baseline interferometry V. High-accuracy orbital parallax and mass of SU Cygni

A. Gallenne, N. R. Evans, P. Kervella +23

Cepheid masses are particularly necessary to help solving the mass discrepancy, while independent distance determinations provide crucial test of the period-luminosity relation and…

Time-Evolution Images of the Hypergiant RW Cephei During the Re-brightening Phase Following the Great Dimming

Narsireddy Anugu, Douglas R. Gies, Rachael M. Roettenbacher +17

Stars with initial masses larger than 8 solar masses undergo substantial mass loss through mechanisms that remain elusive. Unraveling the origins of this mass loss is important for…

CHARA Near-Infrared Imaging of the Yellow Hypergiant Star Cassiopeiae: Convection Cells and Circumstellar Envelope

Narsireddy Anugu, Fabien Baron, John D. Monnier +18

Massive evolved stars such as red supergiants and hypergiants are potential progenitors of Type II supernovae, and they are known for ejecting substantial amounts of matter, up to…

The Orbit and Dynamical Mass of Polaris: Observations with the CHARA Array

Nancy Remage Evans, Gail Schaefer, Alexandre Gallenne +19

The 30 year orbit of the Cepheid Polaris has been followed with observations by the CHARA Array (Center for High Angular Resolution Astronomy) from 2016 through 2021. An additional…

The Orbit and Mass of the Cepheid AW Per

Nancy Remage Evans, Alexandre Gallenne, Pierre Kervella +17

The Cepheid AW Per is a component in a multiple system with a long period orbit. The radial velocities of Griffin (2016) cover the 38 year orbit well. An extensive program of inter…

Orbits and Dynamical Masses for Six Binary Systems in the Hyades Cluster

Guillermo Torres, Gail H. Schaefer, Robert P. Stefanik +8

We report long baseline interferometric observations with the CHARA Array that resolve six previously known double-lined spectroscopic binary systems in the Hyades cluster, with or…

Vortex Fiber Nulling for Exoplanet Observations: First Direct Detection of M Dwarf Companions around HIP 21543, HIP 94666, and HIP 50319

Daniel Echeverri, Jerry W. Xuan, John D. Monnier +35

Vortex fiber nulling (VFN) is a technique for detecting and characterizing faint companions at small separations from their host star. A near-infrared (m) VFN demonstrat…
