We use Spitzer Space Telescope 24 μm data to search for debris disks among 122 AFGKM stars from the ~670 Myr clusters Hyades, Coma Ber, and Praesepe, utilizing a number of advances in data reduction and determining the intrinsic colors of main-sequence stars. For our sample, the 1σ dispersion about the main-sequence V-KS , KS -[24] locus is approximately 3.1%. We identify seven debris disks at 10% or more (≥3σ confidence level) above the expected KS -[24] for purely photospheric emission. The… Expand

THE DECAY OF DEBRIS DISKS AROUND SOLAR-TYPE STARS
We present a Spitzer MIPS study of the decay of debris disk excesses at 24 and 70 ?m for 255 stars of types F4-K2. We have used multiple tests, including consistency between chromospheric and X-rayExpand
Exploring the Effects of Stellar Rotation and Wind Clearing: Debris Disks Around F Stars
We have conducted a study of debris disks around F stars in order to explore correlations between rotation, stellar winds, and circumstellar disks. We obtained new 24 μm photometry from the MultibandExpand
Protoplanetary and Transitional Disks in the Open Stellar Cluster IC 2395
We present new deep UBVRI images and high-resolution multi-object optical spectroscopy of the young (~ 6 - 10 Myr old), relatively nearby (800 pc) open cluster IC 2395. We identify nearly 300 clusterExpand
Debris discs around M stars: non-existence versus non-detection
Motivated by the reported dearth of debris discs around M stars, we use survival models to study the occurrence of planetesimal discs around them. These survival models describe a planetesimal discExpand

A SENSITIVE IDENTIFICATION OF WARM DEBRIS DISKS IN THE SOLAR NEIGHBORHOOD THROUGH PRECISE CALIBRATION OF SATURATED WISE PHOTOMETRY
We present a sensitive search for WISE W3 (12 μm) and W4 (22 μm) excesses from warm optically thin dust around Hipparcos main sequence stars within 75 pc from the Sun. We use contemporaneouslyExpand
The Collisional Evolution of Debris Disks
We explore the collisional decay of disk mass and infrared emission in debris disks. With models, we show that the rate of the decay varies throughout the evolution of the disks, increasing its rateExpand
A WISE view of IRAS debris disks: revising the dust properties
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 planetaryExpand
A Thermal Infrared Imaging Study of Very Low-Mass, Wide Separation Brown Dwarf Companions to Upper Scorpius Stars: Constraining Circumstellar Environments
We present a 3-5um LBT/MMT adaptive optics imaging study of three Upper Scorpius stars with brown dwarf (BD) companions with very low-masses/mass ratios (M_BD < 25M_Jup; M_BD / M_star ~ 1-2%), andExpand
The Faintest WISE Debris Disks: Enhanced Methods for Detection and Verification
In an earlier study, we reported nearly 100 previously unknown dusty debris disks around Hipparcos main-sequence stars within 75 pc by selecting stars with excesses in individual WISE colors. Here,Expand
