“…Briefly, we traced dust grains over a range of grain radii from the EKB throughout the solar system under the influence of gravity, solar radiation pressure and solar wind drag in order to establish a statistical equilibrium density distribution for each grain size. All grains in this model were started in the region 35 < r s < 50 AU, with the orbital elements randomly selected from those of three categories of KBOs in the ratio of Classical : Scattered : Plutinos = 0.67 : 1.00 : 0.25 (Kavelaars et al, 2009). Integration of the grain trajectory was stopped when a grain arrived near the Sun (r s < 0.1 AU) or left the solar system (r s > 200 AU) with net positive orbital energy.…”

The Student Dust Counter (SDC) is an impact dust detector on board the New Horizons Mission to Pluto. SDC was designed to resolve the mass of dust grains in the range of 10 −12 < m < 10 −9 g, covering an approximate size range of 0.5-10 μm in particle radius. The measurements can be directly compared to the prediction of a grain trajectory tracing model of dust originating from Edgeworth-Kuiper Belt (EKB). Comparing our measurements and model prediction is used to estimate the net mass production rate and the ejecta mass distribution power law exponent to beṀ = (8.9 ± 0.5) × 10 5 g/s and α = 3.02 ± 0.04, respectively. Through April 2012, the New Horizons spacecraft reached approximately 23 AU, enabling SDC to map the dust density distribution along its path.

“…The images were taken as part of the Very Wide (VW) segment of the CFHT Legacy Survey (CFHTLS; Jones et al (2006); Kavelaars et al (2009) The images were pre-processed using the Elixer pipeline (Magnier and Cuillandre, 2004). A fine astrometric correction was applied by the TERAPIX dataprocessing center, and the data was stored at the Canadian Astronomical Data Centre (CADC).…”

The Canada-France-Hawaii Telescope Legacy Survey, specifically the Very Wide segment of data, is used to search for possible main-belt comets. In the first data set, 952 separate objects with asteroidal orbits within the main-belt are examined using a three-level technique. First, the full-width-half-maximum of each object is compared to stars of similar magnitude, to look for evidence of a coma. Second, the brightness profiles of each object are compared with three stars of the same magnitude, which are nearby on the image to ensure any extended profile is not due to imaging variations. Finally, the star profiles are subtracted from the asteroid profile and the residuals are compared with the background using an unpaired Ttest. No objects in this survey show evidence of cometary activity. The second survey includes 11438 objects in the main-belt, which are examined visually. One object, an unknown comet, is found to show cometary activity. Its motion is consistent with being a main-belt asteroid, but the observed arc is too short for a definitive orbit calculation. No other body in this survey shows evidence of cometary activity. Upper limits of the number of weakly and strongly active main-belt comets are derived to be 630±77 and 87±28, respectively. These limits are consistent with those expected from asteroid collisions. In addition, data extracted from the Canada-France-Hawaii Telescope image archive of main-belt comet 176P/LINEAR is presented.

“…In most cases observational and selection biases were present. The Canadian-France Ecliptic Plane Survey (CFEPS) was set up at the beginning of the past decade (Kavelaars et al 2009;Petit et al 2011;Gladman et al 2012), developing a discovery and follow-up strategy intended to minimize observational biases and to obtain a population of objects that can be considered representative of all dynamical classes of the trans-Neptunian region (also known as the Edgeworth-Kuiper belt, EKB). As a result of this observational effort involving researchers and facilities in many countries, we begin to understand the overall structure of the trans-Neptunian objects (TNO) populations in terms of dynamical features and absolute magnitude number distributions.…”

The inventory of the populations of trans-Neptunian objects (TNO) has grown considerably over the last decade. As for other groups of small bodies in our solar system, TNOs are expected to have experienced a collisional evolution owing to their mutual impacts. The knowledge of the statistics of collisions, including determination of the rate of mutual collisions and the distribution of the impact velocity, is indeed a fundamental prerequisite for developing models of collisional evolution. We revised the evaluation of those statistical parameters for TNOs provided more than ten years ago on the basis of a much more limited sample of objects than currently available. We used the Canada-France Ecliptic Plane Survey (CFEPS) L7 model to extract an unbiased sample of orbits for TNOs, while the statistical parameters of impact are computed using a statistical tool. We investigated the statistics of impacts among TNOs for the whole population and for different dynamical subgroups. Moreover, we investigated the statistics of collisions between subgroups with crossing orbits. The peculiar dynamical behavior of objects in resonant orbits is taken into account. Our present computation of the probabilities of collision are 20% to 50% lower than previous estimates, while mean impact velocities turn out to be about 70% higher. For instance, the rate of collisions among Plutinos, expressed in terms of the so-called mean intrinsic probability of collision, results to be (3.90 ± 0.01) × 10 −22 km −2 yr −1 and the mean impact velocity is 2.46 ± 0.01 km s −1 . We also find that the distributions of impact velocities seem to be quite different from pure Maxwellian distributions. These results can be useful in developing models of the collisional evolution in the trans-Neptunian region.
