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 Neutron star?Typically between 10 and 25 solar masses
2. What is the core collapse mechanism?Gravitational instability leading to supernova and neutronization
3. What is the associated phenomena?Pulsars, X-ray binaries, millisecond pulsars, gravitational wave sources, kilonovae, short gamma-ray bursts
4. How does a neutron star form?When a massive star runs out of fuel, its core collapses and explodes as a supernova. The collapse squeezes the core so much that electrons and protons combine into neutrons, leaving a very dense remnant.
5. Why do some neutron stars spin so fast?During the collapse, the star’s rotation speeds up, like a spinning ice skater pulling in their arms. Some can spin hundreds of times per second and send out bright beams that look like cosmic lighthouses.

Equation of State: Describes the relationship between pressure, temperature, and density for matter under extreme conditions.
r-process Nucleosynthesis: A nuclear process responsible for creating heavy elements through rapid neutron capture.
Conservation of Angular Momentum: A physical principle stating that the total angular momentum of a system remains constant.
Inverse Beta Decay: A nuclear reaction where a proton and electron combine to form a neutron and a neutrino.
