Abstract About 40 trans-Neptunian binaries (TNBs) have fully determined orbits with about 10 others being solved except for breaking the mirror ambiguity. Despite decades of study, almost all TNBs only ever been analyzed a model that assumes perfect Keplerian motion (e.g., two point masses). In reality, TNB systems are non-Keplerian due to nonspherical shapes, possible presence undetected system components, and/or solar perturbations. this work, we focus on identifying candidates detectable...
Abstract Dynamically studying trans-Neptunian object (TNO) binaries allows us to measure masses and orbits. Most of the known objects appear have only two components, except (47171) Lempo, which is single hierarchical triple system with three similar-mass components. Though hundreds TNOs been imaged high-resolution telescopes, no other triples (or trinaries) found among solar small bodies, even though they are predicted in planetesimal formation models such as gravitational collapse after...

The objective of this research was to investigate the utility ground-penetrating radar (GPR) as a potential tool for detecting inadequate bonding after placement asphalt overlays. This involved field testing pavement segment in city northern Utah that exhibited interlayer between overlay, which underlain by paving fabric, and underlying asphalt. GPR surveys were completed at each 21 coring locations using 2.6 GHz 1.6 antennas, images compared bond condition determined from cores. After...
