Write what each word means, using the article.

Do not copy the article. Write two things you learned, the way you would explain them to a friend.

Answers below are taken from the article’s stored facts, so they match what the student read.

1. How heavy is Red nugget?Approximately 0.6 solar masses
2. What is the stellar remnant type?White dwarf
3. What is the support mechanism?Electron degeneracy pressure
4. How does a red nugget form?When a star like the Sun runs out of hydrogen, it swells into a red giant, fuses helium and heavier elements, then throws off its outer layers, leaving a hot core that becomes a red nugget.
5. Why are red nuggets so dense?The core is squeezed so tightly that electrons can’t share the same space, creating a pressure that pushes outward and keeps the star from collapsing, making it extremely dense.

Electron Degeneracy Pressure: A quantum mechanical pressure arising from the Pauli exclusion principle that prevents electrons from occupying the same quantum state.
Chandrasekhar Limit: The maximum mass a stable white dwarf can have before collapsing under its own gravity or undergoing thermonuclear runaway.
Type Ia Supernova: A powerful stellar explosion that occurs when a white dwarf in a binary system accretes enough mass to exceed the Chandrasekhar limit.
