The Radial Distribution of the Kuiper Belt
We examine the radial distribution of the Kuiper Belt objects (KBOs) using a method that is insensitive to observational bias effects. This technique allows the use of the discovery distances of all KBOs, independent of orbital classification or discovery circumstance. We verify the presence of an outer edge to the Kuiper Belt, as reported in other works, and we measure this edge to be at given...
متن کاملProbing the Radial Distribution of the Kuiper Belt using Stellar
Introduction: The Trans-Neptunian Objects (TNOs) are the frozen leftovers from the formation period of the outer solar system [1]. The current total mass in the Kuiper Belt is estimated to be around 0.03-0.3 Earth masses [2], but there is evidence that a much larger mass (10-40 M Earth) was originally present at the time of formation [3]. The direct observation of the TNOs does not allow reachi...
متن کاملThe Inclination Distribution of the Kuiper Belt
We develop a general method for determining the unbiased inclination distribution of the Kuiper belt using only the inclination and latitude of discovery of known Kuiper belt objects (KBOs). These two parameters are well determined for each discovered object, so we can use all 379 known KBOs (as of 2001 January 1)Èwithout knowing the objectÏs precise orbit, area, detection efficiency, or the la...
متن کاملThe Size Distribution of Kuiper Belt Objects
We describe analytical and numerical collisional evolution calculations for the size distribution of icy bodies in the Kuiper Belt. For a wide range of bulk properties, initial masses, and orbital parameters, our results yield power-law cumulative size distributions, NC ∝ r , with qL ≈ 3.5 for large bodies with radii, r & 10–100 km, and qs ≈ 2.5–3 for small bodies with radii, r . 0.1–1 km. The ...
متن کامل0 The Size Distribution of the Kuiper Belt Objects
The size distribution is determined directly from the current known Kuiper Belt Objects (KBOs). We found that there is a peak for the size distribution around 230 km in diameter. For the objects larger than 230 km, the KBOs populate as N(s) ∝ s as we see in Jewitt et al. (1998). For the objects smaller than 230 km, we found N(s) ∝ s. This result from the current observational data is new and ve...
