04// white dwarfs (and red giants)

hello guys :D

White dwarfs are what low-mass stars leave behind after their death, and red giants are basically the last thing stars are before that. 

White dwarfs are often made mostly of carbon and oxygen, and are very massive, containing at least half of the star in an object as small as the size of the earth. A single teaspoon of a white dwarf would have approx. the mass of a car. They do have a limit tho, and it is called the Chandrasekhar limit (1.44 SM)

They are very hot and small but don't shine as much, so you can't spot them as easily as stars.

White dwarfs will continue to shine for billion billion years, and after that, they'll become cold, black dwarfs - this will probably be the heat death of the universe

tbh this is probably all I can understand lmao 

(feel free to correct me/add stuff!)
