Refinement of the Motion Model of the Linus Satellite of the Asteroid (22) Kalliope

The aim of this article is to analyze the dynamics of the Linus satellite of the asteroid (22) Kalliope. New results have been obtained, and now they are being published. New observations of the satellite were made at the Caucasian Mountain Observatory of Sternberg Astronomical Institute (SAI MSU) from October 2021 to March 2022. The obtained astrometric results are presented in the article. Based on the updated set of observations, the parameters of the satellite’s orbit were redetermined. With the addition of new observations an increase in the accuracy of ephemerides is shown. A new attempt was made to determine the precession of the satellite’s orbit caused by the compression of a rapidly rotating asteroid. The goal was to determine the dynamic compression of the central body. The entire observation interval is divided into groups. From the observations of each group the position of the axis of the satellite’s orbit was found. Changing the position of the axis gives the desired precession. Several case studies show that the axis position of such observation groups is determined very unreliable. The reason is strong correlation between the determinable parameters with limited observation accuracy. Ways of studying precession by jointly defining dynamic parameters based on all available observations have been identified.
