Across
- 2. These stars are much larger than dwarf stars, with diameters ranging from 10 to 100 times that of the Sun. They are less common than dwarf stars and have much shorter lifespans
- 5. The most massive and luminous type of star, with masses exceeding 8 times that of the Sun.
- 7. The most common type of star, with masses ranging from 0.08 to 1.4 times that of the Sun. They are relatively small in size, with a diameter of about 0.1 to 0.8 times that of the Sun.
- 8. This type of "star" looks like a star but its core is not yet hot enough for fusion to take place
- 10. A type of graph that contains information about its temperature, chemical composition, and intrinsic luminosity
Down
- 1. Abbreviated as "HRD", is a scatter plot of stars showing the relationship between the stars' absolute magnitudes or luminosities versus their stellar classifications or effective temperatures
- 3. massive, luminous spheres of plasma that emit light and heat due to the process of nuclear fusion
- 4. A powerful and luminous explosion of a star. This occurs during the last evolutionary stages of a massive star or when a white dwarf is triggered into runaway nuclear fusion.
- 6. These objects arise as a final evolution stage of massive stars. The star has to have mass at least ten times larger than is the mass of Sun.
- 9. A type of emission nebula consisting of an expanding, glowing shell of ionized gas ejected from red giant stars late in their lives.
