Astronomy: Life Cycle of a Low Mass Star (15 of 17) The Planetary Nebula: Stage 12

Visit ilectureonline.com for more math and science lectures!
In this video I will explain what happens when the low mass stars reaches the final stage of its life.

Why does the temperature of Planetary Nebulas increase (why they go to the left on the HR diagram?)?

[@MichelvanBiezen]

The star remnant, when a planetary nebula is formed from the outer layers of the red giant, is a white dwarf which is essentially a collapsed core held up by the electron degeneracy. This white dwarf is very hot and emits a lot of UV radiation. This UV radiation collides with the planetary nebular sorrounding it, causing the nebula to glow.
