Micron-size extrasolar dust particles have been convincingly detected by satellites. Larger extrasolar meteoroids (5-35 μm) have most likely been detected by ground-based radar at Arecibo and New Zealand. We present estimates of the minimum detectable particle sizes and the collecting areas for both radar systems. We show that particles larger than ~10 μm can propagate for tens of parsecs through the interstellar medium, opening up the possibility that ground-based radar systems can detect AGB… 
A search for interstellar meteoroids using the Canadian Meteor Orbit Radar (CMOR)
Using the CMOR system, a search was conducted through 2.5 years (more than 1.5 million orbits) of archived data for meteoroids having unbound hyperbolic orbits around the Sun. Making use of the fact
Dust Outflows and Inner Gaps Generated by Massive Planets in Debris Disks
Main-sequence stars are commonly surrounded by debris disks, formed by cold far-IR-emitting dust that is thought to be continuously replenished by a reservoir of undetected dust-producing
REALISTIC DETECTABILITY OF CLOSE INTERSTELLAR COMETS
During the planet formation process, billions of comets are created and ejected into interstellar space. The detection and characterization of such interstellar comets (ICs) (also known as
PROBING OORT CLOUD AND LOCAL INTERSTELLAR MEDIUM PROPERTIES VIA DUST PRODUCED IN COMETARY COLLISIONS
The Oort cloud remains one of the most poorly explored regions of the solar system. We propose that its properties can be constrained by studying a population of dust grains produced in collisions of
THE DYNAMICS OF DUST GRAINS IN THE OUTER SOLAR SYSTEM
We study the dynamics of large dust grains ≳1 μm with orbits outside of the heliosphere (beyond 250 AU). Motion of the solar system through the interstellar medium (ISM) at a velocity of 26 km s−1

AN OPTICAL SURVEY FOR MILLIMETER-SIZED INTERSTELLAR METEOROIDS
We report high-resolution multi-station observations of meteors by the Canadian Automated Meteor Observatory recorded from 2009 June to 2010 August. Our survey has a limiting detection magnitude of
Some Stars are Totally Metal: A New Mechanism Driving Dust Across Star-Forming Clouds, and Consequences for Planets, Stars, and Galaxies
Dust grains in neutral gas behave as aerodynamic particles, so they can develop large local density fluctuations entirely independent of gas density fluctuations. Specifically, gas turbulence can

Submillimeter studies of main-sequence stars
JCMT maps of the 800-micron emission from Vega, Fomalhaut, and Beta Pictoris are interpreted to indicate that they are not ringed by large reservoirs of distant orbiting dust particles that are too
Dusty Debris around Solar-Type Stars: Temporal Disk Evolution
Using ISO-ISOPHOT, we carried out a survey of almost 150 stars to search for evidence of emission from dust orbiting young main-sequence stars, both in clusters and isolated systems. Over half of the
Dust in the local interstellar wind
The gas-to-dust mass ratios found for interstellar dust within the solar system, versus values determined astronomically for the cloud around the solar system, suggest that large and small
Structure in the Dusty Debris around Vega
We present images of the Vega system obtained with the IRAM Plateau de Bure interferometer at a 1.3 mm wavelength with submillijansky sensitivity and ~2.″5 resolution (about 20 AU). These

A radar meteor facility in operation in the Southern Hemisphere has been constructed so as to provide routine measurements of the heliocentric orbits of Earth-intersecting meteoroids to a limiting
Dust Particle Size Distributions Around Oxygen-Rich Mass-Losing Red Giants
We investigate the size distributions of circumstellar grains around seven oxygen-rich mass-losing red giants by using published data for the spatial extents of the circumstellar OH masers to compare
Large Circumbinary Dust Grains around Evolved Giants
We have detected continuum emission at 450 μm, 850 μm, and 1.35 mm from SS Lep (or 17 Lep), 3 Pup, and probably BM Gem, respectively, which are likely or confirmed binary systems consisting of at
THE SIZE DISTRIBUTION OF ARECIBO INTERSTELLAR PARTICLES AND ITS IMPLICATIONS
Size histograms of all Arecibo ultra-high-frequency radar micrometeors detected in 1997-1998 whose radii were measured by atmospheric drag are presented. Most can be fitted with either a lognormal

A circumstellar disk has been observed optically around the fourth-magnitude star β Pictoris. First detected in the infrared by the Infrared Astronomy Satellite last year, the disk is seen to extend
Physics of Meteoric Phenomena
This monograph deals with the complex physical events accom­ panying the entry into our atmosphere of meteor bodies or meteoroids. These small objects (in the range of 10 -1 2 to 1012 grams),
