| Type |
Description |
| I |
Oxygen-rich non-variable stars without circumstellar shells |
| II |
Variable stars with "young" O-rich circumstellar shells |
| IIIa |
Variable stars with more evolved O-rich circumstellar shells |
| IIIb |
Variable stars with thick O-rich circumstellar shells |
| IV |
Variable stars with very thick O-rich circumstellar shells |
| V |
Planetary nebulae and non- variable stars with very cool circumstellar shells |
| VIa |
Variable stars with relatively cold dust at large distances; a significant part of the stars is carbon-rich |
| VIb |
Variable stars with relatively hot dust close to the star and relatively cold dust at large distances; Some of the objects have proven to be O-rich |
| VII |
Variable stars with more evolved C-rich circumstellar shells |
| VIII |
Different sort of objects |
