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

Possible interstellar meteoroids detected by the Canadian Meteor Orbit Radar

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

High geocentric velocity meteor ablation

Interstellar origin meteoroids have now been detected using radar, image intensified video, large aperture radar and space dust impact techniques. Dynamical and radiation production mechanisms will

Discovery of interstellar dust entering the Earth's atmosphere

ALL known asteroids and comets are believed to have been gravitationally bound to the Sun since they formed (together with the Sun and planets) from the solar nebula. This is because no such object

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 clues

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

Extrasolar Micrometeors Radiating from the Vicinity of the Local Interstellar Bubble

Over 12,000 micrometeor detections obtained mainly during 1997 November 15-20 and over a similar period in 1998 with the Arecibo UHF (430 MHz) radar have been processed so far. Out of this particular

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

We have used the Keck I telescope to obtain images at 11.7 and 18.7 μm of AC Her, a post-asymptotic giant branch spectroscopic binary. The source is resolved into two spots separated by about 0.″6,
