Multiple outflows and delayed ejections revealed by early imaging of novae
Elias Aydi, John D. Monnier, Antoine Mérand +39
Novae are thermonuclear eruptions on accreting white dwarfs in interacting binaries. Although most of the accreted envelope is expelled, the mechanism -- impulsive ejection, multip…
Interferometry of Massive Stars: Multiplicity, Magnetism, and Stellar Winds
H. Sana E. Bordier, K. Deshmukh, A. J. Frost +7
After decades of efforts, optical long-baseline interferometry has become a mainstream observational technique in terms of operation robustness and user friendliness. Interferometr…
Surprise non-detection of Upsilon Andromedae b with MIRC-X and MYSTIC at the CHARA Array
Tyler Gardner, John D. Monnier, Stefan Kraus +11
Ground-based long baseline interferometry is a powerful tool for characterizing exoplanets which are too close to their host star to be imaged with single-dish telescopes. The CHAR…
The Small Separation A-Star Companion Population: Tentative Signatures of Enhanced Multiplicity with Primary Mass
Matthew De Furio, Tyler Gardner, John D. Monnier +6
We present updated results from our near-infrared long-baseline interferometry (LBI) survey to constrain the multiplicity properties of intermediate-mass A-type stars within 80 pc.…
Orbital and Physical Properties of the Pleiades Binary 27 Tau (Atlas)
G. Torres, A. Tkachenko, K. Pavlovski +12
We report new spectroscopic and interferometric observations of the Pleiades binary star Atlas, which played an important role nearly three decades ago in settling the debate over…
HD 143006: Interferometric Confirmation of Misaligned Protoplanetary Disc with CHARA/MIRCX and VLTI/PIONIER
I. Codron, S. Kraus, J. D. Monnier +7
The outer regions of the protoplanetary disc surrounding the T Tauri star HD 143006 show rings, dust asymmetries and shadows. Whilst rings and dust asymmetries can arise from compa…
Precise Age For The Binary HD 21278 In The Young Alpha Persei Cluster
Christopher A. Danner, Eric L. Sandquist, Gail H. Schaefer +14
We present a study of the double-lined spectroscopic binary HD 21278 that contains one of the brightest main sequence stars in the young Persei open cluster. We analyzed new sp…
The Dynamic Inner Disk of a Planet Forming Star
Benjamin R. Setterholm, John D. Monnier, Fabien Baron +13
Planets are a natural byproduct of the stellar formation process, resulting from local aggregations of material within the disks surrounding young stars. Whereas signatures of gas-…
Newborn Be star systems observed shortly after mass transfer
Th. Rivinius, R. Klement, S. D. Chojnowski +24
Many classical Be stars acquire their very rapid rotation by mass and angular-momentum transfer in massive binaries. Short-lived intermediate-phase objects have only been discovere…
A Spectroscopic and Interferometric Study of W Serpentis Stars. I. Circumbinary Outflow in the Interacting Binary W Serpentis
Katherine Shepard, Douglas R. Gies, Gail H. Schaefer +6
W Serpentis is an eclipsing binary system and the prototype of the Serpentid class of variable stars. These are interacting binaries experiencing intense mass transfer and mass los…
