Interferometric Detection and Orbit Modeling of the Subcomponent in the Hot-dust System Tuc A: A Low-mass Star on an Eccentric Orbit in a Hierarchical-quintuple System
T. A. Stuber, A. Mérand, F. Kirchschlager +19
The system Tuc A is part of a hierarchical-quintuple system and is a prime target for studies of hot-exozodiacal dust, because a time-variable near-infrared excess has been de…

Hot exozodiacal dust around Fomalhaut: The MATISSE perspective
Kevin Ollmann, Florian Kirchschlager, Thomas A. Stuber +6
Excess over the stellar photospheric emission of main-sequence stars has been found in interferometric near-infrared observations, and is attributed to the presence of hot exozodia…

Review and prospects of hot exozodiacal dust research for future exo-Earth direct imaging missions
Steve Ertel, Tim D. Pearce, John H. Debes +12
Hot exozodiacal dust is dust in the innermost regions of planetary systems, at temperatures around 1000K to 2000K, and commonly detected by near-infrared interferometry. The phenom…
