Infrared Astronomical Satellite (IRAS) observations in 1983 revealed the existence of several solar system dust bands. These dust bands are believed to be debris produced by recent disruption events among main-belt asteroids, particularly because dust particles have short dynamical and collisional lifetimes. Using young asteroid families as tracers of recent disruptions in the main belt, we linked the most prominent IRAS dust bands with their sources. We propose that the source regions of the…

Physical properties of asteroid dust bands and their sources
The zodiacal dust bands are bright infrared (IR) strips produced by thermal emission from circumsolar rings of particles. Two of the three principal dust bands, known as β and γ, were previously
Signatures of recent asteroid disruptions in the formation and evolution of solar system dust bands
We have performed detailed dynamical modeling of the structure of a faint dust band observed in coadded IRAS data at an ecliptic latitude of 17$^{\circ}$ that convincingly demonstrates that it is the
Evidence from IRAS for a very young, partially formed dust band
Abstract The relative proportions of asteroidal and cometary materials in the zodiacal cloud is an ongoing debate. The determination of the asteroidal component is constrained through the study of
Extreme collisions between planetesimals as the origin of warm dust around a Sun-like star
An exceptionally large amount of warm, small, silicate dust particles around the solar-type star BD+20 307 (HIP 8920, SAO 75016) are reported, which could be explained by recent frequent or huge collisions between asteroids or other ‘planetesimals’ whose orbits are being perturbed by a nearby planet.
Dust in the solar system and in extra-solar planetary systems
Among the observed circumstellar dust envelopes a certain population, planetary debris disks, is ascribed to systems with optically thin dust disks and low gas content. These systems contain
Circumstellar Dust Created by Terrestrial Planet Formation in HD 113766
We present an analysis of the gas-poor circumstellar material in the HD 113766 binary system (F3/F5, 10-16 Myr), recently observed by the Spitzer Space Telescope. For our study we have used the IR
Evolution of Dust Trails into Bands
We use numerical simulations to investigate the production of dust trails by asteroid disruption events. Our work shows that asteroid trails evolve into pairs of dust bands over time. Coherent trails
Asteroids in our solar system formed in a dynamically quiescent disk, but their orbits became gravitationally stirred enough by Jupiter to lead to high-speed collisions. As a result, several dozen
Candidates for Asteroid Dust Trails
The contribution of different sources to the circumsolar dust cloud (known as the zodiacal cloud) can be deduced from diagnostic observations. We used the Spitzer Space Telescope to observe the


The formation and origin of the IRAS zodiacal dust bands as a consequence of single collisions between asteroids
Abstract The zodiacal dust bands discovered by IRAS can be explained as products of single collisions between asteroids. Debris from such a collision is distributed about the plane of the ecliptic as
Zodiacal dust bands - Their relation to asteroid families
Abstract A mathematical model of the spatial distribution of orbitally evolved collisional debris which reproduces the zodiacal dust band phenomenon is developed. The resultant torus has maxima in
First Detection of Visible Zodiacal Dust Bands from Ground-based Observations
We present the first ground-based observational evidence of the zodiacal dust bands originally discovered by the Infrared Astronomical Satellite (IRAS) and confirmed by the Cosmic Background Explorer
The Three-Dimensional Structure of the Zodiacal Dust Bands
Abstract Using observations of the infrared sky brightness by the Cosmic Background Explorer (COBE) 1 Diffuse Infrared Background Experiment (DIRBE) and Infrared Astronomical Satellite (IRAS), we
The recent breakup of an asteroid in the main-belt region
The discovery of a family of asteroids that formed in a disruption event only 5.8 ± 0.2 million years ago, and which has subsequently undergone little dynamical and collisional evolution, is reported.
Zodiacal emission. III - Dust near the asteroid belt
Properties of the zodiacal dust bands are derived from fits to Infrared Astronomical Satellite profiles of the ecliptic. Three observations lead to the conclusion that the dust-band material is
Extended sources of far-infrared emission superposed on the zodiacal and galactic backgrounds are found at high galactic latitudes and near the ecliptic plane. Clouds of interstellar dust at color

Recent observations of the size–frequency distribution of zodiacal cloud particles obtained from the cratering record on the LDEF satellite are the latest evidence for a significant large particle
IRAS observations of extended zodiacal structures
In 1983, the Infrared Astronomical Satellite discovered two pairs of dust bands, straddling the ecliptic plane and located in the asteroid belt. New analysis of the IRAS data has resulted in the
Origin of the Solar System dust bands discovered by IRAS
Measurements of longitudinal variations in the brightness and the latitude of the Solar System dust bands observed by the Infrared Astronomical Satellite determine the orbital elements of the
