Sergey V. Ershkov,R. V. Shamin +1 more
TL;DR: In this article, an analytical exploration of the dynamics of asteroid rotation when it moves in an elliptic orbit through Space is presented, where an elegant example for evolution of spin towards the rotation about maximal-inertia axis is calculated.

On a new type of solving procedure for Euler–Poisson equations (rigid body rotation over the fixed point)
TL;DR: In this paper, the Euler-Poisson equations are reduced to a system of three nonlinear ordinary differential equations of first order in regard to three functions, and the proper elegant approximate solution has been obtained as a set of quasi-periodic cycles via re-inversing the proper elliptical integral.

A procedure for the construction of non-stationary Riccati-type flows for incompressible 3D Navier–Stokes equations
TL;DR: In this article, the authors explore the ansatz of derivation of non-stationary solution for the Navier-Stokes equations in the case of incompressible flow, which was suggested earlier.

On the dynamics OF NON-RIGID asteroid rotation
TL;DR: In this paper, the authors presented a new solving procedure for the dynamics of non-rigid asteroid rotation, considering the final spin state of rotation for a small celestial body (asteroid).
