Pre-nova Observations of T CrB: A view from the CHARA Array
Ryan Norris, Narsireddy Anugu, Thomas Gaudin +38
T CrB is a symbiotic recurrent nova consisting of a red giant and white dwarf with recent eruptions in 1866 and 1946 and an anticipated eruption in the mid 2020s. We report CHARA A…
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…
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 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-…
