The dust sublimation region of the Type 1 AGN NGC4151 at a hundred micro-arcsecond scale as resolved by the CHARA Array interferometer

Makoto Kishimoto, Matt Anderson, Theo ten Brummelaar +10

The nuclear region of Type 1 AGNs has only been partially resolved so far in the near-infrared (IR) where we expect to see the dust sublimation region and the nucleus directly with…

Establishing Oph as a Prototype Rotator: Precision Orbit with new Keck, CHARA, and RV Observations

Tyler Gardner, John D. Monnier, Francis C. Fekel +11

Alpha Ophiuchi (Rasalhague) is a nearby rapidly rotating A5IV star which has been imaged by infrared interferometry. Oph is also part of a known binary system, with a companion…
