EXPRES. III. Revealing the Stellar Activity Radial Velocity Signature of Eridani with Photometry and Interferometry

Rachael M. Roettenbacher, Samuel H. C. Cabot, Debra A. Fischer +20

The distortions of absorption line profiles caused by photospheric brightness variations on the surfaces of cool, main-sequence stars can mimic or overwhelm radial velocity (RV) sh…

Gem: a hierarchical triple system with an outer Be star

Robert Klement, Petr Hadrava, Thomas Rivinius +17

Time series of spectroscopic, speckle-interferometric, and optical long-baseline-interferometric observations confirm that Gem is a hierarchical triple system. It consists of a…

The First Dynamical Mass Determination of a Nitrogen-rich Wolf-Rayet Star using a Combined Visual and Spectroscopic Orbit

Noel D. Richardson, Laura Lee, Gail Schaefer +11

We present the first visual orbit for the nitrogen-rich Wolf-Rayet binary, WR 133 (WN5o + O9I) based on observations made with the CHARA Array and the MIRC-X combiner. This orbit r…

The orbit and stellar masses of the archetype colliding-wind binary WR 140

Joshua D. Thomas, Noel D. Richardson, J. J. Eldridge +33

We present updated orbital elements for the Wolf-Rayet (WR) binary WR\,140 (HD\,193793; WC7pd + O5.5fc). The new orbital elements were derived using previously published measuremen…
