PHOTOMETRIC STUDY OF NPA ROTATOR (5247) KRYLOV

. The light curve phases with P-1 and this indicate that it is a typical Non-Principal Axis (NPA) asteroid. We discuss the possible causes of its NPA rotation.We conduct BVRI and R band photometric observa...

The tumbling spin state of (99942) Apophis

Our photometric observations of Asteroid (99942) Apophis from December 2012 to April 2013 revealed it to be in a state of non-principal axis rotation (tumbling excited Short Axis Mode (SAM) state ...

Stress field and spin axis relaxation for inelastic triaxial ellipsoids

A compact formula for the stress tensor inside a self-gravitating, triaxial ellipsoid in an arbitrary rotation state is given. It contains no singularity to derive a solution for the energy dissipation resulting in the damping (short-axi...
