Exozodiacal clouds: Hot and warm dust around main sequence stars
Quentin Kral, Alexander V. Krivov, Denis Defrere +7
A warm/hot dust component (at temperature 300K) has been detected around 20% of stars. This component is called "exozodiacal dust" as it presents similarities with the z…

This review focuses on numerical approaches to deducing the light-scattering and thermal-emission properties of primitive dust particles in planetary systems from astronomical obse…
Models of the Eta Corvi debris disk from the Keck Interferometer, Spitzer and Herschel
J. Lebreton, C. Beichman, G. Bryden +4
Debris disks are signposts of analogues to small body populations of the Solar System, often however with much higher masses and dust production rates. The disk associated with the…
An Unbiased Near-infrared Interferometric Survey for Hot Exozodiacal Dust
Steve Ertel, Jean-Charles Augereau, Olivier Absil +5
Exozodiacal dust is warm or hot dust found in the inner regions of planetary systems orbiting main sequence stars, in or around their habitable zones. The dust can be the most lumi…
First-light LBT nulling interferometric observations: warm exozodiacal dust resolved within a few AU of eta Corvi
D. Defrère, P. M. Hinz, A. J. Skemer +37
We report on the first nulling interferometric observations with the Large Binocular Telescope Interferometer (LBTI), resolving the N' band (9.81 - 12.41 um) emission around the ne…
Exo-zodi modelling for the Large Binocular Telescope Interferometer
Grant M. Kennedy, Mark C. Wyatt, Vanessa Bailey +18
Habitable zone dust levels are a key unknown that must be understood to ensure the success of future space missions to image Earth analogues around nearby stars. Current detection…
Searching for faint companions with VLTI/PIONIER. II. 92 main sequence stars from the Exozodi survey
Lindsay Marion, Olivier Absil, Steve Ertel +6
The Exozodi survey aims to determine the occurrence rate of bright exozodiacal discs around nearby main sequence stars using infrared interferometry. Although the Exozodi survey ta…
