One Winged Angel /
- Stars, overlapping with Clipped-Wing Angel. For example, the first form of a star with more or less the mass of the Sun is a star of medium size, luminosity, and temperature. Once hydrogen is exhausted on the star's core, it takes its second form becoming much larger, luminous, and cooler until helium fusion ensues and it takes its third form, a star much smaller and less luminous than its second one but still more luminous, larger, and cooler than its first. When core helium is used up, it takes a fourth form, very similar to the second one. This one, however, is rather a Clipped-Wing Angel since it's unstable pulsating and shedding material until finally what remains of the star is a cooling stellar corpse with the size of a planet.. All other stars suffer in their evolution more or less dramatic changes, especially in what refers to their remnants, but those similar to ours in mass are the ones that more dramatically increase their luminosities.
