Recent and Upcoming Upgrades for MIRC-X and MYSTIC on the CHARA Array

Noura Ibrahim, Mayra Gutierrez, John D. Monnier +17

MIRC-X and MYSTIC are six-telescope near-infrared beam (1.08-2.38 m) combiners at the CHARA Array on Mt Wilson CA, USA. Ever since the commissioning of MIRC-X (J and H bands) in…

CHARA Near-Infrared Imaging of the Yellow Hypergiant Star Cassiopeiae: Convection Cells and Circumstellar Envelope

Narsireddy Anugu, Fabien Baron, John D. Monnier +18

Massive evolved stars such as red supergiants and hypergiants are potential progenitors of Type II supernovae, and they are known for ejecting substantial amounts of matter, up to…

Refining the Stellar Parameters of Ceti: a Pole-on Solar Analog

Maria Korolik, Rachael M. Roettenbacher, Debra A. Fischer +16

To accurately characterize the planets a star may be hosting, stellar parameters must first be well-determined. Ceti is a nearby solar analog and often a target for exoplanet s…

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…
