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…

Multiplicity of northern bright O-type stars with optical long baseline interferometry

Cyprien Lanthermann, Jean-Baptiste Le Bouquin, Hugues Sana +16

The study of the multiplicity of massive stars gives hints on their formation processes and their evolutionary paths, which are still not fully understood. Large separation binarie…

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…

Interferometric detections of sdO companions orbiting three classical Be stars

R. Klement, G. H. Schaefer, D. R. Gies +17

Classical Be stars are possible products of close binary evolution, in which the mass donor becomes a hot, stripped O or B-type subdwarf (sdO/sdB), and the mass gainer spins up and…
