Evolution of protoplanetary disc
This WWW-page contains two short videos concerning the once existing proto-planetary disc in the Solar System.

Content:
- protopl_evol.avi
- the animation of the evolution of the proto-planetary disc during
the first giga-year of its existence
- the view from the Pole
- the part of the disc from 4 to 50 astronomical units (Earth-Sun
distances) was considered
- the red, green, blue, and violet ellipses (almost identical with
the circles) illustrate the orbits of Jupiter, Saturn, Uranus, and
Neptune; the radius of the outer-most planet, Neptune, is about
30 astronomical units
- protopl_final.avi
- the "sightseeing" of the proto-planetary disc, described in (1),
in the time of 1 giga-year after its formation
- the bodies close at the Jupiter's orbit (red ellipse) are well-
known Trojans of this planet
- the bodies beyond the orbit of Neptune (violet ellipse) are the
trans-Neptunian objects, the existence of which was confirmed only
recently, in the beginning of ninety nineties, when the first of
them were discovered
- protopl_evol.avi
- protopl_final.avi
These videos were created with help of the data gained within the
scientific research (comprehending a robust numerical integration of
the orbits of 10038 test particles perturbed by the giant planets,
Galactic tide, and nearly passing stars for 1 giga-year period),
the results of which will be published in the following articles:

of the evolution", Astronomy and Astrophysics, submitted.
- Leto G., Jakubik M., Paulech T., Neslusan L., Dybczynski P.A.: 2008,
"The structure of the inner Oort cloud from the simulation of its
formation for two giga-years", in preparation.
