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 MoM-z14 known for?Significant source of ejected carbon and oxygen, enriching the interstellar medium
2. What is the spectral classification?WC-type Wolf-Rayet star, indicating prominent carbon and oxygen emission lines
3. What is the surface temperature?Exceeds 50,000 Kelvin, contributing to its extreme luminosity and UV output
4. Why does MoM-z14 have such strong winds?The star is extremely hot (over 50,000 K) and massive, so its powerful winds push away its outer layers at a rate of about a solar mass each year.
5. How does MoM-z14 help new stars and planets form?The winds carry heavy elements like carbon and oxygen into space, enriching the interstellar medium and giving future stars the ingredients needed to build planets.

Wolf-Rayet star: An evolved, massive star that has lost its outer hydrogen envelope, characterized by strong stellar winds and emission lines of heavier elements.
Stellar winds: A continuous outflow of plasma from a star's atmosphere, far more energetic and dense in Wolf-Rayet stars than in Sun-like stars.
Interstellar medium (ISM): The diffuse matter and radiation filling the space between stars, crucial for galactic evolution and star formation.
Nucleosynthesis: The process by which new atomic nuclei are created within stars and through stellar explosions.
