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 long is Young stellar object?Primarily studied in infrared and submillimeter wavelengths due to dust obscuration
2. What is the classification system?Based on spectral energy distribution (Class 0, I, II, III)
3. What is the primary energy source?Gravitational potential energy conversion during accretion
4. How does a young star grow?The star grows by pulling in gas and dust from its disk. The material falls onto the protostar, heating it and giving the star more mass.
5. Why do young stars have jets?Many young stars shoot out fast jets from their poles. The jets help the star get rid of extra spinning motion so it can keep pulling in more material.

Gravitational Collapse: The process where a cloud of gas and dust shrinks under its own gravity.
Protostar: The earliest stage of a star's life, characterized by accretion and heating before nuclear fusion.
Bipolar Jets: Collimated streams of gas ejected from the poles of a protostar, crucial for angular momentum removal.
Accretion Disk: A rotating disk of gas and dust surrounding a young star, feeding its growth and forming planets.
