By searching the IRAS and ISO databases, we compiled a list of 60 debris disks that exhibit the highest fractional luminosity values (fd > 10-4) in the vicinity of the Sun (d < 120 pc). Eleven out of these 60 systems are new discoveries. Special care was taken to exclude bogus disks from the sample. We computed the fractional luminosity values using available IRAS, ISO, and Spitzer data and analyzed the Galactic space velocities of the objects. The results revealed that stars with disks of high… 

The debris disk candidates: eleven 24 μm excess stars in the Spitzer SWIRE fields

We present the optical to mid-infrared SEDs of 11 debris disk candidates from Spitzer SWIRE fields. All the candidates are selected from SWIRE 24 μm sources matched with both the SDSS star catalog


Although photometric and spectroscopic surveys with the Spitzer Space Telescope remarkably increased the number of well-studied debris disks around A-type and Sun-like stars, detailed analyses of

Debris Disks around Sun-like Stars

We have observed nearly 200 FGK stars at 24 and 70 μm with the Spitzer Space Telescope. We identify excess infrared emission, including a number of cases where the observed flux is more than 10 times

Debris disks around stars are considered as components of planetary systems. Constraining the dust properties of these disks can give crucial information to formation and evolution of planetary


We cross-correlate the Hipparcos main-sequence star catalog with the AKARI/FIS catalog and identify 136 stars (at >90% reliability) with far-infrared detections in at least one band. After rejecting

Searching for debris discs in the 30 Myr open cluster IC 4665

Context. Debris discs orbiting young stars are key to understanding dust evolution and the planetary formation process. We take advantage of a recent membership analysis of the 30 Myr nearby open

A Direct Imaging Survey of Spitzer-detected Debris Disks: Occurrence of Giant Planets in Dusty Systems

We describe a joint high-contrast imaging survey for planets at the Keck and Very Large Telescope of the last large sample of debris disks identified by the Spitzer Space Telescope. No new substellar

Characterization of Dusty Debris Disks: The IRAS and Hipparcos Catalogs

Dusty debris disks around main-sequence stars are signposts for the existence of planetesimals and exoplanets. From cross-correlating Hipparcos stars with the IRAS catalogs, we identify 146 stars

The hybrid disks: a search and study to better understand evolution of disks

The increased sensitivity of millimeter-wave facilities now makes possible the detection of low amounts of gas in debris disks. Some of the gas-rich debris disks harbor peculiar properties, with

Search for cold debris disks around M-dwarfs. II

Although 70% of the stars in the Galaxy are M-dwarfs, thermal emission searches for cold debris disks have been conducted mostly for A-type and solar-type stars. We report on new λ = 1.2 mm continuum



Decay of Planetary Debris Disks

We report new Spitzer 24 μm photometry of 76 main-sequence A-type stars. We combine these results with previously reported Spitzer 24 μm data and 24 and 25 μm photometry from the Infrared Space

Frequency of Debris Disks around Solar-Type Stars: First Results from a Spitzer MIPS Survey

We have searched for infrared excesses around a well-defined sample of 69 FGK main-sequence field stars. These stars were selected without regard to their age, metallicity, or any previous detection

Planets and Infrared Excesses: Preliminary Results from a Spitzer MIPS Survey of Solar-Type Stars

As part of a large Spitzer MIPS Guaranteed Time Observation program, we have searched for infrared excesses due to debris disks toward 26 FGK field stars known from radial velocity (RV) studies to

Incidence and survival of remnant disks around main-sequence stars

We present photometric ISO 60 and 170 um measurements, complemented by some IRAS data at 60 ${\mu\textrm{m}}$, of a sample of 84 nearby main-sequence stars of spectral class A, F, G and K in order to

Constraining the Lifetime of Circumstellar Disks in the Terrestrial Planet Zone: A Mid-Infrared Survey of the 30 Myr old Tucana-Horologium Association

We have conducted an N-band survey of 14 young stars in the ~30 Myr old Tucana-Horologium association to search for evidence of warm, circumstellar dust disks. Using the MIRAC-BLINC camera on the

Spitzer Space Telescope Observations of G Dwarfs in the Pleiades: Circumstellar Debris Disks at 100 Myr Age* **

Fluxes and upper limits in the wavelength range from 3.6 to 70 μm from the Spitzer Space Telescope are provided for 20 solar-mass Pleiades members. One of these stars shows a probable mid-IR excess,

Formation and Evolution of Planetary Systems: Cold Outer Disks Associated with Sun-like Stars

We present the discovery of debris systems around three Sun-like stars based on observations performed with the Spitzer Space Telescope as part of a Legacy Science Program, "The Formation and

A Resolved Debris Disk around the G2 V Star HD 107146

We present resolved scattered-light images of the debris disk around HD 107146, a G2 star 28.5 pc from the Sun. This is the first debris disk to be resolved in scattered light around a solar-type

First Optical Images of Circumstellar Dust Surrounding the Debris Disk Candidate HD 32297

Near-infrared imaging with the Hubble Space Telescope recently revealed a circumstellar dust disk around the A star HD 32297. Dust-scattered light is detected as far as 400 AU radius, and the linear
