You are cordially invited to the SCL seminar of the Center for the Study of Complex Systems, which will be held on Thursday, 19 March 2026 at 15:00 in the library reading room "Dr. Dragan Popović" of the Institute of Physics Belgrade. The talk entitled

From discs of gas and dust to planets and planetesimals

will be given by Marija Janković (Scientific Computing Laboratory, Institute of Physics Belgrade). The abstract of the talk:

Today we know about thousands of planets outside of Solar system. Planets form in discs of gas and dust that surround young stars. In this gas and dust it is small planetesimals that form first, and then the planets. After a few million years, these discs disperse, and what remains are not only planets, but also rings of planetesimals which did not grow - asteroids and comets. Planetesimals and planets continue to evolve for billions of years, due to stellar irradiation, mutual gravitational interactions and mutual collisions. In this talk we will cover numerical research of these and other phenomena that shape planetary systems, and also the most recent astrophysical observations which can be used to test our theories.
