n-Body: Gravitation, Ladung, Expansion

[Yukterez]

Ableitung der Position p nach der Zeit t in abstandstreuen Koordinaten, Beschleunigung:



mit der Distanz d zwischen den jeweiligen Körpern i und j:



und der Coulomb-Konstante k:



Wenn die Expansion des Universums berücksichtigt wird ist die kosmologische Konstante



Schwerpunkt des Systems:



Zwei Körper bleiben stationär zueinander wenn das Ladung/Masse-Verhältnis



wobei f eine beliebige Zahl ist. Mit berücksichtigter Expansion ist das Gleichgewicht beim Abstand/Masse-Verhältnis



Notation: Newton. Variablen: M=Masse, Q=Ladung, p=Position, v=Geschwindigkeit, G=Gravitationskonstante, ε₀=Feldkonstante, Λ=Lambda.

3 Körper, links: symmetrische Startpositionen, rechts: asymmetrisch; t: Sekunden

2 mit Q=M√(G/k) geladene und 1 neutraler Körper (grün); links: masseloser Testpartikel, rechts: massiver neutraler Drittkörper

6 Körper, zufällig gewählte Startbedingungen; links: Seitenansicht, rechts: Draufsicht, Schweiflänge: 100 sek

8 Körper mit jeweils 10¹⁰ kg, geschlossene Orbits in symmetrischer Anordnung:

Diskussion: hier und hier

[Yukterez]

Instabile geschlossene Orbits mit 5 Körpern; t: Sekunden, Periodendauer: 2π sek, M=m³/sek²/G, Schweiflänge: 1 sek

Instabile geschlossene Orbits mit 5 Körpern; Periodendauer: 2π sek, M=m³/sek²/G, Schweiflänge: π/3 sek

Stationäre Punkte markieren die Startpositionen. Die Startbedingungen für die Ensembles wurden von Carles Simó ausgearbeitet.

[Yukterez]

Mehrkörpersimulatoren für Masse und Ladung. Masselose Testpartikel sind erlaubt, ebenso negative und selbstverständlich positive Massen. Geladene Körper müssen jedoch Masse haben da sie ohne im elektromagnetischen Feld aufgrund der ansonsten fehlenden Trägheit unter Krafteinwirkung unendlich stark beschleunigen würden.
