PolskiProtoplanetary Disk Accretion (2D)
Top-down 2D dust-accretion lab: Kepler-orbiting grains collide and stick into planetesimals and protoplanets around a young star, with adjustable time speed, dust density and stickiness.
This 2D companion drives the same Kepler-orbit, probabilistic-merger accretion model as the 3D version through a flat top-down view: dust grains circle a young star faster the closer they orbit, nearby grains merge with a probability set by the stickiness slider while conserving mass, and growing bodies are reclassified from dust to planetesimal to protoplanet — all easier to read at a glance than in the orbiting 3D scene.
