A One of a Kind, Unique, Real‑Time Solar System Formation Simulation Engine
Written by: Astrophyzix Digital Observatory
Introduction
Astrophyzix is proud to announce the release of SolarForm, a scientifically rigorous, real‑time simulation engine that models the birth and evolution of a planetary system from the collapse of a protoplanetary nebula to the emergence of planetesimals, proto‑planets, and gas giants.
SolarForm is designed as an educational scientific module, providing the public, students, and astronomy enthusiasts with a clear, interactive way to explore the physics that shaped our Solar System. The module is powered by real astrophysical equations, peer‑reviewed models, and a direct N‑body gravitational integrator.
A Real‑Time Window Into Planetary Formation
SolarForm simulates the early stages of solar system formation using physically grounded models drawn from astrophysics, celestial mechanics, and planetary science. Users can watch a nebular disk evolve dynamically as bodies collide, merge, accrete, and migrate under gravity.
Key features include:
- N‑body gravitational physics using a velocity‑Verlet symplectic integrator.
- Planetesimal growth and accretion through inelastic collisions with gravitational focusing.
- Protoplanetary disk density profiles based on the Minimum Mass Solar Nebula (MMSN).
- Keplerian orbital initialization scaled by nebula mass and angular momentum.
- Snowline physics determining where ice bodies and gas giant cores can form.
- Real‑time classification of bodies into planetesimals, proto‑planets, rocky planets, and gas giants.
The simulation updates continuously, allowing users to observe the chaotic, emergent behaviour of early planetary systems as they stabilize over time.
