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 B-type main-sequence star?1.8 M☉ to 10 M☉
2. What is the spectral type?B-type main-sequence star
3. What is the effective surface temperature range?10,000 K to 30,000 K
4. What makes B-type main-sequence stars so hot and bright?They have surface temperatures between 10,000 and 30,000 K and are many times more massive than the Sun, so they burn hydrogen very fast and shine thousands of times brighter.
5. How long do B-type stars live compared to the Sun?They live only a few tens to a few hundred million years, much shorter than the Sun's billions of years, because they use up their fuel quickly.

Hertzsprung-Russell Diagram: A scatter plot of stars showing the relationship between their luminosity and surface temperature.
Hydrostatic Equilibrium: The balance between the inward pull of gravity and the outward push of pressure within a star.
Photoionization: The ionization of an atom or molecule by absorbing a photon of sufficient energy, typically ultraviolet radiation.
Nucleosynthesis: The process by which elements are created within stars by nuclear fusion.
