Asteroid pairs: method validation and new candidates

Candidates for Asteroid Dust Trails

The contribution of different sources to the circumsolar dust cloud (known as the zodiacal cloud) can be deduced from diagnostic observations. We used the Spitzer Space Telescope to observe the diffuse thermal emission of the zodiacal cloud near the ecliptic. Several structures were identified in these observations, including previously known asteroid dust bands, which are thought to have been ...

Spectro-photometry of Dynamically Assocaited Asteroid Pairs

Geometric mechanics and the dynamics of asteroid pairs.

The purpose of this paper is to describe the general setting for the application of techniques from geometric mechanics and dynamical systems to the problem of asteroid pairs. The paper also gives some preliminary results on transport calculations and the associated problem of calculating binary asteroid escape rates. The dynamics of an asteroid pair, consisting of two irregularly shaped astero...

New findings on asteroid spin-vector distributions

The number of known spin vectors of main belt and near-Earth asteroids is regularly growing, including new objects, and updating the estimates concerning known cases, with the aid of new observations and of improved observational techniques. A reliable statistical analysis of the spin vectors is now possible. In general the poles (both for MB bodies and for NEAs) are not isotropically distribut...

Detection Method of Scallop and Asteroid from Seabed Video

Recently, the investigation method has been developed to measure fishes using an underwater video camera. These methods can investigate the benthic fishery resources, but the acoustic survey cannot. However, these investigations do not use automatic measurements from the videos but only taken the videos. In this paper, we propose a method to count the scallop and the asteroid from the seabed vi...
