Five steps in the evolution from protoplanetary to debris disk
Mark C. Wyatt, Olja Panic, Grant M. Kennedy +1
The protoplanetary disks of Herbig Ae stars eventually dissipate leaving a tenuous debris disk comprised of planetesimals and dust, as well as possibly gas and planets. This paper…
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…
Nature or nurture of coplanar Tatooines: the aligned circumbinary Kuiper belt analogue around HD 131511
Grant M. Kennedy
A key discovery of the Kepler mission is of the circumbinary planets known as "Tatooines", which appear to be well aligned with their host stars' orbits. Whether this alignment is…
Interpreting the extended emission around three nearby debris disc host stars
Jonathan P. Marshall, F. Kirchschlager, S. Ertel +7
Cool debris discs are a relic of the planetesimal formation process around their host star, analogous to the solar system's Edgeworth-Kuiper belt. As such, they can be used as a pr…
Do Two Temperature Debris Disks Have Multiple Belts?
Grant M. Kennedy, Mark C. Wyatt
We present a study of debris disks whose spectra are well modelled by dust emission at two different temperatures. These disks are typically assumed to be a sign of multiple belts,…
Towards Chemical Constraints on Hot Jupiter Migration
Nikku Madhusudhan, Mustafa A. Amin, Grant M. Kennedy
The origin of hot Jupiters -- gas giant exoplanets orbiting very close to their host stars -- is a long-standing puzzle. Planet formation theories suggest that such planets are unl…
The Debris Disk of Solar Analogue Ceti: Herschel Observations and Dynamical Simulations of the Proposed Multiplanet System
S. M. Lawler, J. Di Francesco, G. M. Kennedy +16
Ceti is a nearby, mature G-type star very similar to our Sun, with a massive Kuiper Belt analogue (Greaves et al. 2004) and possible multiplanet system (Tuomi et al. 2013) that…
Correlations between the stellar, planetary and debris components of exoplanet systems observed by
J. P. Marshall, A. Moro-Martín, C. Eiroa +18
The DEBRIS, DUNES and GT programmes observed 37 exoplanet host stars within 25 pc at 70, 100 and 160 m with the sensitivity to detect far-infrared excess emi…
