TL;DR: In this article, a reliable statistical analysis of the spin vectors of the main belt and near-Earth asteroids is presented, with the aid of new observations and of improved observational techniques, and the importance of new observational campaigns, mainly devoted to compute the poles of small bodies and of the members of asteroid dynamical families.

TL;DR: In this article, the authors investigated whether the Yarkovsky- Radzievskii-O'Keefe-Paddack (YORP) thermal radiation effect could have produced these unusual spin states.

TL;DR: In this paper, the influence of the initial variations vector is explained in the context of Lyapunov vectors theory and some selection rules are recommended for spectral and variational methods.

TL;DR: In this paper, the authors describe numerical tools for the stability analysis of extrasolar planetary systems and apply the tangent map to derive a numerically efficient algorithm of the fast indicator Mean Exponential Growth Factor of Nearby Orbits (MEGNO), a measure of the maximal Lyapunov exponent, that helps to distinguish chaotic and regular configurations.

TL;DR: The spin state of small asteroids can change on a long timescale by the Yarkovsky-O'Keefe-Radzievskii-Paddack (YORP) effect, the net torque that arises from anisotropic scattered sunlight and proper thermal radiation from an irregularly-shaped asteroid as discussed by the authors.
