Scheme of phenomena from the Fokin & Gillet (1997) model (RR41) during a pulsation cycle.
| φ interval | Phenomenon |
|---|---|
| 0.75–0.80 | The κ−γ mechanism associated with He-ionization and H-ionization zones provokes local overpressure, which transforms into outward progressive waves w1 and w2. |
| 0.80/0.93 | w1 and w2 rapidly become shocks s1 and s2, which emerge from the photosphere. |
| 0.96 | s1 merges with secondary shocks. |
| 1.01 | s2 merges with s1; apparition of the main shock. |
| 1.05 | The main shock leaves the described atmosphere. |
| 1.35 | Maximum expansion of the photosphere. |
| 1.60 | Maximum expansion of the highest atmospheric layers. |
