The HOSTS Survey for Exozodiacal Dust: Preliminary results and future prospects
S. Ertel, G. M. Kennedy, D. Defrère +40
[abridged] The presence of large amounts of dust in the habitable zones of nearby stars is a significant obstacle for future exo-Earth imaging missions. We executed an N band nulli…
Using warm dust to constrain unseen planets
Amy Bonsor, Mark C. Wyatt, Quentin Kral +3
Cold outer debris belts orbit a significant fraction of stars, many of which are planet-hosts. Radiative forces from the star lead to dust particles leaving the outer belts and spi…
Limits on the number of primordial Scattered Disk objects at Pluto mass and higher from the absence of their dynamical signatures on the present day trans-Neptunian Populations
Andrew Shannon, Rebekah I. Dawson
Today, Pluto and Eris are the largest and most massive Trans-Neptunian Objects respectively. They are believed to be the last remnants of a population of planetesimals that has bee…
Constraining the presence of giant planets in two-belt debris disk systems with VLT/SPHERE direct imaging and dynamical arguments
Elisabeth Matthews, Sasha Hinkley, Arthur Vigan +10
Giant, wide-separation planets often lie in the gap between multiple, distinct rings of circumstellar debris: this is the case for the HR\,8799 and HD\,95086 systems, and even the…
Exoplanet recycling in massive white-dwarf debris discs
Rik van Lieshout, Quentin Kral, Sébastien Charnoz +2
Several tens of white dwarfs are known to host circumstellar discs of dusty debris, thought to arise from the tidal disruption of rocky bodies originating in the star's remnant pla…
The HOSTS survey - Exozodiacal dust measurements for 30 stars
S. Ertel, D. Defrère, P. Hinz +40
The HOSTS (Hunt for Observable Signatures of Terrestrial Systems) survey searches for dust near the habitable zones (HZs) around nearby, bright main sequence stars. We use nulling…
