Question

Understand the mass range of stars and how this is related to their spectral classification, their temperatures, luminosities and lifetimes.

Answer 1

Stars of different masses have different spectral classifications, temperatures, luminosities, and lifetimes.

Step-by-step explanation:

Stars come in a wide range of masses, which impacts various aspects of their properties, including their spectral classification, temperatures, luminosities, and lifetimes.

Spectral classification is a system used to categorize stars based on their surface temperature. This classification is denoted by a letter, such as O, B, A, F, G, K, and M, with each letter representing a specific range of temperatures. For example, O-type stars are the hottest, while M-type stars are the coolest.

The mass of a star directly affects its temperature, luminosity, and lifespan. Generally, stars with higher masses have higher temperatures, greater luminosities, and shorter lifetimes. In contrast, stars with lower masses have lower temperatures, lower luminosities, and longer lifetimes.
