Planetary System Formation Process

A Planetary System Formation Process is a stellar system accretion-based astronomical process that transforms protoplanetary disks around young stars into organized planetary systems through gravitational aggregation.

• AKA: Planet Formation Process, Planetary Accretion Process, Solar System Formation Process.
• Context:
  • It can typically aggregate Planetary System Dust Grains through planetary system electrostatic forces and planetary system van der Waals forces.
  • It can typically form Planetary System Planetesimals via planetary system gravitational instabilityes and planetary system collisional growth.
  • It can typically generate Planetary System Protoplanets through planetary system runaway accretions and planetary system oligarchic growth.
  • It can typically differentiate Planetary System Composition Zones creating planetary system rocky planets and planetary system gas giants.
  • It can typically establish Planetary System Orbital Architectures with planetary system resonances and planetary system migration patterns.
  • ...
  • It can often require Planetary System Metallicity Levels providing planetary system solid materials for planetary system core formation.
  • It can often involve Planetary System Disk Evolutions including planetary system photoevaporations and planetary system viscous spreading.
  • It can often exhibit Planetary System Dynamical Instabilityes causing planetary system orbital rearrangements and planetary system body ejections.
  • It can often produce Planetary System Debris Disks from planetary system collision fragments and planetary system leftover materials.
  • ...
  • It can range from being a Terrestrial Planetary System Formation Process to being a Giant Planetary System Formation Process, depending on its planetary system mass accumulation.
  • It can range from being a Core Accretion Planetary System Formation Process to being a Disk Instability Planetary System Formation Process, depending on its planetary system growth mechanism.
  • It can range from being a In-Situ Planetary System Formation Process to being a Migration Planetary System Formation Process, depending on its planetary system orbital evolution.
  • It can range from being a Single Star Planetary System Formation Process to being a Binary Star Planetary System Formation Process, depending on its planetary system stellar environment.
  • It can range from being a Metal-Rich Planetary System Formation Process to being a Metal-Poor Planetary System Formation Process, depending on its planetary system element abundance.
  • ...
  • It can integrate with Star Formation Processes for planetary system initial condition.
  • It can connect to Cosmic Goldilocks Conditions for planetary system habitability potential.
  • It can interface with Asteroid Belt Formations for planetary system small body distribution.
  • It can synchronize with Moon Formation Processes for planetary system satellite creation.
  • It can relate to Exoplanet Discoverys for planetary system diversity understanding.
  • ...
• Example(s):
  • Solar System Planetary System Formation Process (4.6 billion years ago), such as:
    • Inner Solar System Planetary System Formation Process, creating planetary system terrestrial planets within planetary system frost line.
    • Outer Solar System Planetary System Formation Process, forming planetary system gas giants beyond planetary system ice boundary.
    • Asteroid Belt Planetary System Formation Process, preserving planetary system planetesimals prevented from planetary system planet coalescence.
  • Exoplanetary System Formation Processes, such as:
    • Hot Jupiter Planetary System Formation Process, producing planetary system gas giants through planetary system inward migration.
    • Super-Earth Planetary System Formation Process, creating planetary system intermediate-mass planets absent in Solar System.
    • Circumbinary Planetary System Formation Process, forming planetary system planets around planetary system binary stars.
  • Theoretical Planetary System Formation Processes, such as:
    • Pebble Accretion Planetary System Formation Process, rapidly growing planetary system cores from planetary system centimeter-sized particles.
    • Gravitational Instability Planetary System Formation Process, directly forming planetary system gas giants from planetary system disk fragmentation.
  • Failed Planetary System Formation Processes, such as:
    • Brown Dwarf Planetary System Formation Process, creating planetary system substellar objects below planetary system fusion threshold.
    • Rogue Planet Planetary System Formation Process, producing planetary system ejected bodyes without planetary system stellar orbit.
  • ...
• Counter-Example(s):
  • Stellar Formation Process, which creates stars rather than planets unlike planetary system formation processes.
  • Galaxy Formation Process, which operates at larger scales than individual planetary system formation processes.
  • Asteroid Collision Event, which destroys rather than builds planetary bodyes unlike planetary system formation processes.
  • Planetary Ring Formation, which creates ring systems rather than solid planets of planetary system formation processes.
