White dwarf stars can range in temperature from well over 100000K to about 4000K.
Faraday John Cage: a mesh container that's perfectly soundproof in both directions, but only for four minutes and thirty-three seconds at a time.
White dwarfs stars don’t undergo fusion, they are inert balls of electron degenerate gas that are slowly cooling. How slow? Takes about 10 billion years.
Stars smaller than the Sun don’t form planetary nebulae. As their cores turn into white dwarfs they don’t get hot enough to cause the ejected gas to glow.
Net neutrality as a phone analogy: Net neutrality, you pick up your Telus phone and call your Bell customer friend and the call goes through, no extra charges or slowdowns. No net neutrality: You pick up your Telus phone and you're told you can call your friend for an extra fee.
Achy and coughing... I've got a bad feeling about this...
After all it's fuel is expended. All it's outer layers ejected. Our Sun will end its days as a white dwarf star. A remnant of our Sun's core slowly cooling as it drifts through space.
In general terms, more low to intermediate mass stars are formed in a galaxy over time than larger mass stars.
Proto-planetary nebulae are a stage of stellar evolution between asymptotic giant branch stars and planetary nebulae. PPNe have characteristics of both AGB stars and PNe. PPN IRAS17106-3046 shown, image from Hubble Space Telescope data. https://octodon.social/media/EFskOOaoy26limvz0CY
Looking at astronomy as a hobby? Before sinking money into a telescope why not try a pair of binoculars? Way cheaper, easier to use, and a great way to learn the night sky.
Asymptotic Giant Branch (AGB) stars undergo massive mass loss. So much so they basically eject the non-core layers of the stars into space by the end of this phase of stellar evolution.
