In search of the source of asteroid (101955) Bennu: Applications of the stochastic YORP model

Popis výsledku v původním jazyce

Asteroid (101955) Bennu, the target of NASA's OSIRIS-REx sample return mission, is a D approximate to 0.5 km diameter low albedo near-Earth object. It has a spectral signature consistent with primitive carbonaceous chondrites, and an orbit similar to that of the Earth. A plausible evolution scenario for Bennu is that it migrated inward across the inner main belt from a low albedo family by Yarkovsky thermal forces over many hundreds of Myr. Eventually, it entered a resonance that took it into the terrestrial planet region, where a combination of planetary encounters and resonances took it to its current orbit over a few Myr to tens of Myr. When it departed the main belt, Bennu probably had an eccentricity 0.1 < e < 0.2 and an inclination 1 degrees < i< 6 degrees. Several low albedo families have the appropriate dynamical, color, albedo, and broad spectral characteristics to produce Bennu: Clarissa, Erigone, Eulalia, New Polana, and Sulamitis. Here we used a suite of numerical simulati
