- 12 April 2014
Context. Hot exozodiacal dust is thought to be responsible for excess near-infrared (NIR) emission emanating from the innermost parts of some debris disks. The origin of this dust, however, is still…
An interferometric study of the Fomalhaut inner debris disk: III. Detailed models of the exozodiacal disk and its origin
- J. Lebreton, R. Lieshout, P. Th'ebault
- Physics, Geology
- 5 June 2013
Context. Debris disks are thought to be extrasolar analogs to the solar system planetesimal belts. The star Fomalhaut harbors a cold debris belt at 140 AU comparable to the Edgeworth-Kuiper belt, as…
Dusty tails of evaporating exoplanets - I. Constraints on the dust composition
- R. Lieshout, M. Min, C. Dominik
- Geology, Physics
- 13 October 2014
Context. Recently, two exoplanet candidates have been discovered, KIC 12557548b and KOI-2700b, whose transit profiles show evidence of a comet-like tail of dust trailing the planet, thought to be fed…

A dearth of small particles in the transiting material around the white dwarf WD 1145+017
- S. Xu, S. Rappaport, B. Zuckerman
- Physics, Geology
- 19 November 2017
White dwarf WD 1145+017 is orbited by several clouds of dust, possibly emanating from actively disintegrating bodies. These dust clouds reveal themselves through deep, broad, and evolving transits in…

Modelling the KIC8462852 light curves: compatibility of the dips and secular dimming with an exocomet interpretation
- M. Wyatt, R. Lieshout, G. Kennedy, T. Boyajian
- Physics, Geology
- 16 October 2017
This paper shows how the dips and secular dimming in the KIC8462852 light curve can originate in circumstellar material distributed around a single elliptical orbit (e.g. exocomets). The expected…
Dusty tails of evaporating exoplanets. II. Physical modelling of the KIC 12557548b light curve
- R. Lieshout, M. Min, T. V. Werkhoven
- Geology, Physics
- 1 September 2016
Evaporating rocky exoplanets, such as KIC 12557548b, eject large amounts of dust grains, which can trail the planet in a comet-like tail. When such objects occult their host star, the resulting…
THE INNER DEBRIS STRUCTURE IN THE FOMALHAUT PLANETARY SYSTEM
- K. Su, G. Rieke, Chin-Fei Lee
- Physics, Geology
- 11 December 2015
Fomalhaut plays an important role in the study of debris disks and small bodies in other planetary systems. The proximity and luminosity of the star make key features of its debris, like the water…
