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…

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…

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 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…

The orbital kinematics of eta Carinae over three periastra with a possible detection of the elusive secondary's motion

Emily Strawn, Noel D. Richardson, Anthony F. J. Moffat +14

The binary eta Carinae is the closest example of a very massive star, which may have formed through a merger during its Great Eruption in the mid-nineteenth century. We aimed to co…

Changes in the Na D Absorption Components of Carinae Provide Clues on the Location of the Dissipating Central Occulter

Connor S. Pickett, Noel D. Richardson, Theodore Gull +9

The Na D absorption doublet in the spectrum of Carinae is complex, with multiple absorption features associated with the Great Eruption (1840s), the Lesser Eruption (1890s), an…

Five years of BRITE-Constellation photometry of the luminous blue variable P Cygni: properties of the stochastic low-frequency variability

Ashley Elliott, Noel D. Richardson, Herbert Pablo +9

Luminous Blue Variables (LBVs) are massive stars that are likely to be a transitionary phase between O stars and hydrogen-free classical Wolf-Rayet stars. The variability of these…
