Understanding Star Classification: Color and Surface Temperature

The video tutorial explains how stars are classified based on their color and temperature. It introduces the concept of luminosity, comparing the energy output of different stars like red dwarfs, the sun, and Wolf-Rayet stars. The classification table is discussed, showing how stars are grouped by color and surface temperature. The video also explores the relationship between a star's intensity, wavelength, and temperature, illustrating how peak wavelengths shift with temperature changes. The tutorial concludes by summarizing the connection between a star's color, temperature, and luminosity.

Describe how the peak wavelength of a star changes with temperature.

How does the color of a star relate to its luminosity?

What happens to the energy emitted per unit area as a star's temperature increases?
