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 a Type Ib supernova?A Type Ib supernova is a star explosion that has lost its outer hydrogen layer but still has helium. The explosion shows strong helium lines in its spectrum.
2. What is a Type Ic supernova?A Type Ic supernova is a star explosion that has lost both its hydrogen and helium layers. Its spectrum shows lines of heavier elements like oxygen and calcium.

Wolf-Rayet Star: A hot, massive star characterized by strong stellar winds and the absence of hydrogen in its spectrum, often a progenitor of stripped-envelope supernovae.
Metallicity: In astronomy, the abundance of elements heavier than helium in a star or celestial object.
r-process: The rapid neutron-capture process responsible for synthesizing elements heavier than iron in extreme astrophysical environments like supernovae.
Collapsar Model: A theoretical framework explaining long-duration gamma-ray bursts and associated supernovae as arising from the collapse of a rapidly rotating massive star's core.
