| | A substantial part of near-Earth asteroids (NEAs) are binary systems.
More than twenty binaries have been discovered among NEAs up to the present, about half of them
with the lightcurve photometry technique. A knowledge of parameters of those systems is
important for understanding of their origin and evolution. I describe the technique of
numerical modeling of binary asteroids which simulates the long-period lightcurve component
showing occultation and/or eclipse events. With this technique, I constrained parameters of the
mutual orbit and secondary´s size for a few near-Earth asteroids. The estimated parameters are
secondary-to-primary size ratio, sidereal orbital period, semimajor axis,
ecliptic coordinates of the normal of the mutual orbit, eccentricity, and length of pericenter.
The results are presented as well. | | Presenting author: | Peter Scheirich |
