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. What is the progenitor star types?Massive stars (core-collapse) and white dwarfs in accreting binary systems (Type Ia)
2. What is the observational techniques?Photometric monitoring for transient events and spectroscopic analysis for classification and composition
3. What is a supernova candidate?It is a star that shows signs it might soon explode as a supernova.
4. Why do some stars explode as supernovae?When a star’s core can no longer support itself, it collapses and rebounds, or a white dwarf gains too much mass and starts runaway fusion.

Chandrasekhar Limit: The maximum mass a stable white dwarf star can have before collapsing under its own gravity.
Galactic Chemical Evolution: The process by which the abundance of chemical elements in a galaxy changes over time due to stellar processes.
Standard Candle: An astronomical object with a known intrinsic luminosity, used to measure cosmic distances.
