   5# Stellar Evolution from J-Cost — Tier F Astronomy
   6
   7Stellar evolution proceeds through canonical phases. In RS terms, each
   8phase transition occurs when the stellar recognition ratio crosses the
   9canonical J(phi) band.

  11Five canonical stellar evolution phases (main sequence, subgiant,
  12red giant, horizontal branch, white dwarf/remnant) = configDim D = 5.

  14RS prediction: phase transition durations on phi-ladder.
