The 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...
متن کاملThe Absolute Magnitude Distribution of Kuiper Belt Objects
Here we measure the absolute magnitude distributions (H-distribution) of the dynamically excited and quiescent (hot and cold) Kuiper Belt objects (KBOs), and test if they share the same H-distribution as the Jupiter Trojans. From a compilation of all useable ecliptic surveys, we find that the KBO H-distributions are well described by broken power-laws. The cold population has a bright-end slope...
متن کاملThe Bimodal Color Distribution of Small Kuiper Belt Objects
We conducted a two-night photometric survey of small Kuiper Belt objects (KBOs) near opposition using the wide-field Hyper Suprime-Cam instrument on the 8.2m Subaru Telescope. The survey covered about 90deg of sky, with each field imaged in the g and i bands. We detected 356 KBOs, ranging in absolute magnitude from 6.5 to 10.4. Filtering for high-inclination objects within the hot KBO populat...
متن کاملSatellites of the Largest Kuiper Belt Objects
We have searched the four brightest objects in the Kuiper Belt for the presence of satellites using the newly commissioned Keck Observatory Laser Guide Star Adaptive Optics system. Satellites are seen around three of the four objects: Pluto (whose satellite Charon is well-known and whose recently discovered smaller satellites are too faint to be detected), 2003 EL61 (where a second satellite is...
