Dependencies

What this concept builds on and what it makes possible — derived from the atlas’s dependency, causal and structural relations, not from every related edge.

Open Solar wind →

solar wind depends on Sun.

Mechanism: The solar wind is a stream of charged particles blown continuously off the Sun.

System context

Sunis part ofSolar SystemEstablished

Open Solar System →

Sun is part of Solar System.

Mechanism: The Sun is the central star of the Solar System; its gravity holds every planet, moon and comet in orbit and its light powers them.

Sources:
Sunis aStarEstablished

Open Star →

Sun is a kind of star.

Mechanism: The Sun is a star — an ordinary main-sequence star that appears huge and bright only because it is so close to Earth.

Sources:
Sunspotis part ofSunEstablished

Open Sunspot →

sunspot is part of Sun.

Mechanism: A sunspot is a cooler, darker patch on the Sun's surface where intense magnetic fields suppress the flow of heat from below.

Structural role & consequence

Interpreted from the current atlas graph — what the connections mean, not just how many there are.

  • Currently dark in the atlas: no key date stored · 4 of 4 of its relations lack claim-level evidence.

    atlas representation · Describes the current Thinking OS representation, not the state of the world.

  • Structural neighbourhood: 4 → 31 → 70 concepts reachable within 3 hops.

    structural · Structural reach — being reachable is not the same as being understood.

  • All 4 of its relationships stay within its own discipline — a field-specific concept in the current atlas.

    structural · Structural graph analysis — not a claim of importance, causation or history.

Strengths & constraints

Constraints

  • Evidence coverage currently thin in the atlas — few of its relationships carry claim-level evidence. atlas representation
  • No dated history stored — the atlas records no key date for this concept. atlas representation

Conditions

  • Read structurally — most of its relationships carry no external evidence yet, so claims here are graph-derived. structural

What builds on this

1 concept build on this directly, 1 in total, across 1 discipline.

Astronomy

Structural downstream reach along dependency edges — not a claim of historical necessity.

Seen through each discipline

How this concept sits in each of its fields — derived from its real connections in the graph, not asserted.

Astronomy

Through this lens it connects to Star, Solar System, Sunspot and Solar wind.
