Modelling the KIC8462852 light curves: compatibility of the dips and secular dimming with an exocomet interpretation
M. C. Wyatt, R. van Lieshout, G. M. Kennedy +1
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., exocomet…
Disintegrating Rocky Exoplanets
Rik van Lieshout, Saul Rappaport
We discuss a new class of exoplanets that appear to be emitting a tail of dusty effluents. These disintegrating planets are found close to their host stars and have very hot, and l…
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…
Infrared observations of white dwarfs and the implications for the accretion of dusty planetary material
Amy Bonsor, Jay Farihi, Mark C. Wyatt +1
Infrared excesses around metal polluted white dwarfs have been associated with the accretion of dusty, planetary material. This work analyses the available infrared data for an unb…
Dusty tails of evaporating exoplanets. II. Physical modelling of the KIC 12557548b light curve
R. van Lieshout, M. Min, C. Dominik +7
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 Inner Debris Structure in the Fomalhaut Planetary System
Kate Y. L. Su, George H. Rieke, Denis Defrere +5
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…
Dusty tails of evaporating exoplanets. I. Constraints on the dust composition
R. van Lieshout, M. Min, C. Dominik
Recently, two exoplanet candidates have been discovered, KIC 12557548b and KOI-2700b, whose transit profiles show evidence for a comet-like tail of dust trailing the planet, though…
Near-infrared emission from sublimating dust in collisionally active debris disks
R. van Lieshout, C. Dominik, M. Kama +1
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,…
An interferometric study of the Fomalhaut inner debris disk. III. Detailed models of the exozodiacal disk and its origin
J. Lebreton, R. van Lieshout, J. -C. Augereau +15
[Abridged] Debris disks are extrasolar analogs to the solar system planetesimal belts. The star Fomalhaut harbors a cold debris belt at 140 AU as well as evidence of a warm dust co…
Activity of comets: Gas Transport in the Near-Surface Porous Layers of a Cometary Nucleus
Yu. Skorov, R. van Lieshout, J. Blum +1
The gas transport through non-volatile random porous media is investigated numerically. We extend our previous research of the transport of molecules inside the uppermost layer of…
An Inner Gaseous Disk around the Herbig Be Star MWC 147
T. Bagnoli, R. van Lieshout, L. B. F. M. Waters +5
We present high-spectral-resolution, optical spectra of the Herbig Be star MWC 147, in which we spectrally resolve several emission lines, including the [O I] lines at 6300 and 636…
