Abstract:
The near-Earth asteroid 3200 Phaethon (1983 TB) is an attractive
object not only from a scientific viewpoint but also because of JAXA's
DESTINY+ target. The rotational lightcurve and spin properties were
investigated based on the data obtained in the ground-based
observation campaign of Phaethon.
We aim to refine the lightcurves and shape model of Phaethon using all
available lightcurve datasets obtained via optical observation, as
well as our time-series observation data from the 2017 apparition.
Using eight 1-2-m telescopes and an optical imager, we acquired the
optical lightcurves and derived the spin parameters of Phaethon. We
applied the lightcurve inversion method and SAGE (Shaping Asteroids
with Genetic Evolution) algorithm to deduce the convex and non-convex
shape model and pole orientations.
Description:
The files contain asteroid brightness, aspect data and observing
information for corresponding date. These files were used for
obtaining synodic period rotation and shape model. Individual
lightcurves within a files are identified with a light curve number,
all lightcurves are relative magnitude.
