The nature of mid-infrared excesses from hot dust around Sun-like stars

  title={The nature of mid-infrared excesses from hot dust around Sun-like stars},
  author={R. Smith and M. Wyatt and W. Dent},
  journal={Astronomy and Astrophysics},
Aims. Studies of the debris disk phenomenon have shown that most systems are analogous to the Edgeworth-Kuiper Belt (EKB). However a rare subset of sun-like stars possess dust which lies, in contrast, in the terrestrial planet region. In this study we aim to determine how many sources with apparent mid-infrared excess are truly hosts of warm dust, and investigate where the dust in these systems must lie. Methods. We observed using ground-based mid-infrared imaging with TIMMI2, VISIR and… Expand
Warm dusty discs: exploring the A star 24 μm debris population
Aims. Studies of the debris disc phenomenon have shown that most systems are analogous to the Edgeworth-Kuiper belt (EKB). In this study we aim to determine how many of the IRAS 25 μm excessesExpand
Resolving the hot dust around HD69830 and η Corvi with MIDI and VISIR
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 inferredExpand
The bright end of the exo-Zodi luminosity function: disc evolution and implications for exo-Earth detectability
We present the first characterisation of the 12µm warm dust (‘exo-Zodi’) luminosity function around Sun-like stars, focusing on the dustiest systems that can be identified by the WISE mission. We useExpand
The discovery of new warm debris disks around F-type stars
We report the discovery of four rare debris disks with warm excesses around F-stars, significantly increasing the number of such systems known in the solar neighborhood. Three of the disks areExpand
Multi-Epoch Observations Of Hd 69830: High-Resolution Spectroscopy And Limits To Variability
The main-sequence solar-type star HD 69830 has an unusually large amount of dusty debris orbiting close to three planets found via the radial velocity technique. In order to explore the dynamicalExpand
Models of the η Corvi Debris Disk from the Keck Interferometer, Spitzer, and Herschel
Debris disks are signposts of analogs to small-body populations of the solar system, often, however, with much higher masses and dust production rates. The disk associated with the nearby star η CrvExpand
The Nearby, Young, Isolated, Dusty Star HD 166191
We report an in-depth study of the F8-type star HD 166191, identified in an ongoing survey for stars exhibiting infrared emission above their expected photospheres in the Wide-field Infrared SurveyExpand
We present nulling interferometric observations of six nearby main-sequence stars (α CrB, α Lyr, β Leo, γ Ser, Eri, and ζ Lep). None of the stars show evidence for a positive detection of warm debrisExpand
Resolved imaging of the HD 191089 debris disc
Two-thirds of the F star members of the 12 Myr old β Pictoris moving group (BPMG) show significant excess emission in the mid-infrared, several million years after the expected dispersal of theExpand
Hot debris dust around HD 106797
Photometry of the A0 V main-sequence star HD 106797 with AKARI and Gemini/T-ReCS is used to detect excess emission over the expected stellar photospheric emission between 10 and 20 micron, which isExpand


Mid-infrared images of β Pictoris and the possible role of planetesimal collisions in the central disk
Thermal infrared images of the central disk imply that the brightness asymmetry results from the presence of a bright clump composed of particles that may differ in size from dust elsewhere in the disk, which is suggested to result from the collisional grinding of resonantly trapped planetesimals or the cataclysmic break-up of a planetesimal.

Dust depletion in the inner disk of β Pictoris as a possible indicator of planets
IT is not yet possible to see planets orbiting other stars, although this may soon change as observing methods improve1. Indirect evidence for the presence of circumstellar dust disks out of whichExpand

We have used the infrared mineralogical model derived from the Spitzer IRS observations of the Deep Impact experiment to study the nature of the dust in the debris found around the K0 V star HDExpand
A near-infrared interferometric survey of debris disk stars. I. Probing the hot dust content aroun
Context. The quest for hot dust in the central region of debris disks re quires high resolution and high dynamic range imaging. Nearinfrared interferometry is a powerful means to directly det ectExpand
Submillimetre images of dusty debris around nearby stars
Indirect detections of massive — presumably Jupiter-like — planets orbiting nearby Sun-like stars have recently been reported,. Rocky, Earth-like planets are much more difficult to detect, but cluesExpand
High spatial resolution mid-infrared observations of the low-mass young star TW Hydrae
Aims. We want to improve knowledge of the structure of the inner few AU of the circumstellar disk around the nearby T Tauri star TW Hya. Earlier studies have suggested the existence of a large innerExpand
Circumstellar material in the Vega inner system revealed by CHARA/FLUOR
Context. Only a handful of debris disks have been imaged up to now. Due to the need for high dynamic range and high angular resolution, very little is known about the inner planetary region, whereExpand
