The Small Separation A-Star Companion Population: First Results with CHARA/MIRC-X
Matthew De Furio, Tyler Gardner, John Monnier +9
We present preliminary results from our long-baseline interferometry (LBI) survey to constrain the multiplicity properties of intermediate-mass A-type stars within 80pc. Previous m…
The Orbits and Dynamical Masses of the Castor System
Guillermo Torres, Gail H. Schaefer, John D. Monnier +12
Castor is a system of six stars in which the two brighter objects, Castor A and B, revolve around each other every 450 yr and are both short-period spectroscopic binaries. Th…
Dynamical masses of the primary Be star and the secondary sdB star in the single-lined binary kappa Dra (B6 IIIe)
R. Klement, D. Baade, Th. Rivinius +16
Because many classical Be stars may owe their nature to mass and angular-momentum transfer in a close binary, the present masses, temperatures, and radii of their components are of…
ARMADA II: Further Detections of Inner Companions to Intermediate Mass Binaries with Micro-Arcsecond Astrometry at CHARA and VLTI
Tyler Gardner, John D. Monnier, Francis C. Fekel +18
We started a survey with CHARA/MIRC-X and VLTI/GRAVITY to search for low mass companions orbiting individual components of intermediate mass binary systems. With the incredible pre…
Characterising the orbit and circumstellar environment of the high-mass binary MWC 166 A
Sebastian A. Zarrilli, Stefan Kraus, Alexander Kreplin +13
Context: Stellar evolution models are highly dependent on accurate mass estimates, especially for high-mass stars in the early stages of evolution. The most direct method for obtai…
A detailed analysis of the Gl 486 planetary system
J. A. Caballero, E. Gonzalez-Alvarez, M. Brady +64
The Gl 486 system consists of a very nearby, relatively bright, weakly active M3.5 V star at just 8 pc with a warm transiting rocky planet of about 1.3 R_Terra and 3.0 M_Terra that…
The Interferometric Binary Epsilon Cancri in Praesepe: Precise Masses and Age
Leslie M. Morales, Eric L. Sandquist, Gail H. Schaefer +16
We observe the brightest member of the Praesepe cluster, Epsilon Cancri, to precisely measure the characteristics of the stars in this binary system, en route to a new measurement…
Scattering and sublimation: a multi-scale view of m-sized dust in the inclined disc of HD 145718
Claire L. Davies, Evan A. Rich, Tim J. Harries +15
We present multi-instrument observations of the disc around the Herbig~Ae star, HD~145718, employing geometric and Monte Carlo radiative transfer models to explore the disc orienta…
