Steady State Evolution of Debris Disks around A Stars
- M. C. Wyatt, R. Smith, +4 authors G. Bryden
- Physics
- 23 March 2007
In this paper a simple analytical model for the steady-state evolution of debris disks due to collisions is confronted with Spitzer observations of dust around main sequence A stars. All stars are… Expand
Molecular Gas Clumps from the Destruction of Icy Bodies in the β Pictoris Debris Disk
- W. Dent, M. C. Wyatt, +11 authors D. Wilner
- Physics, Medicine
- Science
- 28 March 2014
One-Sided Story from Disk In young analogs of the solar system, the ongoing erosion of comets and nascent planets produces dusty debris that is eventually expelled by the host star. Gas should also… Expand
The Vega debris disk: A surprise from spitzer
We present high spatial resolution mid- and far-infrared images of the Vega debris disk obtained with the Multiband Imaging Photometer for Spitzer (MIPS). The disk is well resolved, and its angular… Expand
Resolving the hot dust around HD69830 and η Corvi with MIDI and VISIR
- R. Smith, M. C. Wyatt, C. Haniff
- Physics
- 19 June 2009
Aims. Most of the known debris discs exhibit cool dust in regions analogous to the Edgeworth-Kuiper Belt. However, a rare subset show hot excess from within a few AU, which moreover is often inferred… Expand
CONSTRAINING THE EXOZODIACAL LUMINOSITY FUNCTION OF MAIN-SEQUENCE STARS: COMPLETE RESULTS FROM THE KECK NULLER MID-INFRARED SURVEYS
- B. Mennesson, R. Millan-Gabet, +14 authors J. Woillez
- Physics
- 8 December 2014
Forty-seven nearby main-sequence stars were surveyed with the Keck Interferometer mid-infrared Nulling instrument (KIN) between 2008 and 2011, searching for faint resolved emission from exozodiacal… Expand
Deep 10 and 18 Micron Imaging of the HR 4796A Circumstellar Disk: Transient Dust Particles and Tentative Evidence for a Brightness Asymmetry
- C. Telesco, R. S. Fisher, +12 authors Cfa
- Physics
- 21 September 1999
We present new 10.8 and 18.2 km images of HR 4796A, a young A0 V star that was recently dis- covered to have a spectacular, nearly edge-on, circumstellar disk prominent at D20 km (Jayawardhana and… Expand
Debris disks as signposts of terrestrial planet formation
- S. Raymond, P. Armitage, +6 authors A. West
- Physics
- 31 March 2011
There exists strong circumstantial evidence from their eccentric orbits that most of the known extra-solar planetary systems are the survivors of violent dynamical instabilities. Here we explore the… Expand
The history of the Solar system's debris disc: observable properties of the Kuiper belt
- M. Booth, M. C. Wyatt, +14 authors Boulder
- Physics
- 19 June 2009
The Nice model of Gomes et al. suggests that the migration of the giant planets caused a planetesimal clearing event, which led to the late heavy bombardment (LHB) at 880 Myr. Here, we investigate… Expand
99 Herculis: host to a circumbinary polar‐ring debris disc
- G. Kennedy, M. C. Wyatt, +6 authors M. Fitzgerald
- Physics
- 9 January 2012
We present resolved Herschel images of a circumbinary debris disk in the 99 Herculis system. The primary is a late F-type star. The binary orbit is well characterised and we conclude that the disk is… Expand
Herschel imaging of 61 Vir: implications for the prevalence of debris in low-mass planetary systems
- M. C. Wyatt, G. Kennedy, +15 authors D. Wilner
- Physics
- 11 June 2012
This paper describes Herschel observations of the nearby (8.5pc) G5V multi-exoplanet host star 61Vir at 70, 100, 160, 250, 350 and 500m carried out as part of the DEBRIS survey. These observations… Expand
