Most stars are classified as dwarfs, including the Sun. These stars lie on the main sequence, the phase of life in which a star steadily converts the hydrogen fuel in its core to helium. When the core hydrogen has been depleted, the star gets larger, cooler, and brighter. It becomes first a subgiant, then a giant. Especially massive stars may become bright giants or

12. Star Classification | Physical Geography - Lumen Learning
Bigger stars produce more energy, so their surfaces are hotter. These stars tend toward bluish white. Smaller stars produce less energy. Their surfaces are less ...
Think about how the color of a piece of metal changes with temperature. A coil of an electric stove will start out black but with added heat will start to glow a dull red. With more heat the coil turns a brighter red, then orange. At extremely high temperatures the coil will turn yellow-white, or even blue-white (it’s hard to imagine a stove coil getting that hot). A star’s color is also determined by the temperature of the star’s surface. Relatively cool stars are red, warmer stars are orange or yellow, and extremely hot stars are blue or blue-white.Color is the most common way to classify stars. Table below shows the classification system. The class of a star is given by a letter. Each letter corresponds to a color, and also to a range of temperatures. Note that these letters don’t match the color names; they are left over from an older system that is no longer used. For most stars, surface temperature is also related to size. Bigger stars produce more energy, so their surfaces are hotter. These stars tend toward bluish white. Smaller stars produce less energy. Their surfaces are less hot and so they tend to be yellowish.
13. Dwarf Star: Types, Characteristics, and More Exciting Features

Similarly, the B-type star Rigel, at top left, has a temperature of about 15,000 K and a luminosity more than 10,000 times that of the Sun. The M-type star ...
Astronomers use luminosity and surface temperature to classify stars in much the same way that height and weight serve to classify the bulk properties of human beings. We know that people's height and weight are well correlatedtall people tend to weigh more than short ones. We might naturally wonder if the two basic stellar properties are also related in some way.
