Chandrasekhar limit (Lane–Emden toy)
White-dwarf M–R track for n = 3/2 cold degenerate electrons; UR n = 3 marks the ~1.44 M☉ scale (μ_e dependent).
Cosmological Expansion (FLRW)
a(t), z, χ and c/H vs time; flat Ω_m + Λ (toy ΛCDM).
CMB Power Spectrum (Acoustic Peaks)
Cosmic Microwave Background temperature D_ℓ vs ℓ with Sakharov peaks: tune Ω_b h², Ω_c h², n_s, A_s, τ, h and watch the parity flip between odd / even peaks, the Silk damping tail, and the Sachs–Wolfe plateau move. Pedagogical parametric ΛCDM model.
Big Bang Nucleosynthesis (BBN)
Light-element abundance curves H, ⁴He, D, ³He, ⁷Li vs cosmic time / temperature. Weak freeze-out, neutron decay gap, deuterium bottleneck → Y_p ≈ 0.245. Slide η₁₀ and N_eff over the classic BBN curves; observed values overlaid.
Single-Layer Climate (Toy)
S, α, ε: T_eff vs T_surface from gray-slab balance — intuition only.
Neutron star TOV: toy M–R (polytrope)
Schwarzschild TOV for polytropes n = 1 or 3/2; K normalized so the ρ_c scan peaks near ~2 M☉ (schematic only).
