Computation of asteroid proper elements on the Grid [PDF]

Serbian Astronomical Journal, 2009
A procedure of gridification of the computation of asteroid proper orbital elements is described. The need to speed up the time consuming computations and make them more efficient is justified by the large increase of observational data expected from the

Asteroid spin-rate studies using large sky-field surveys

Geoscience Letters, 2017
Eight campaigns to survey asteroid rotation periods have been carried out using the intermediate Palomar Transient Factory in the past 3 years. 2780 reliable rotation periods were obtained, from which we identified two new super-fast rotators (SFRs ...

The spin state of asteroid Apophis and a prediction of its change during the 2029 close encounter with Earth

Astronomy & Astrophysics
Context. On April 13, 2029, the asteroid Apophis will pass near Earth at a geocentric distance of about 38 000 km. This will provide a unique opportunity to study the effects of Earth’s gravitational torque on the asteroid’s spin state and figure ...

Misaligned Rings Around Minor Planets with Moons

Universe
Recent observations have confirmed the existence of rings around minor bodies in the outer solar system. These objects may possess satellites as well. Here, we analytically investigate the interaction between such rings and satellites.
