White Dwarfs

It’s white and small. What is it? It’s a white dwarf. What’s a white dwarf? Well, it's a stellar core remnant composed of electron-degenerate matter of stars less than ten times the size of the Sun. White dwarfs are really dense. How dense? One teaspoon of white dwarf matter would weigh 15 tons. White dwarfs are usually a little bigger than the Moon. Did you know that there is a white dwarf that is really expensive? A white dwarf named Lucy is 90% diamond. Lucy is about the size of the Moon. So, Lucy is over a 1.8e24 dollars. This means 1.8 times 10 to the power of 24. But it looks like no one is going to get even a good fraction of that amount of money anytime soon. But white dwarfs are the remnant of the smaller stars. What about the bigger ones? Besides becoming a black hole.
