What is the difference between a white dwarf and a red dwarf?
“Dwarf” is a general term for stars with smaller masses. Our Sun is termed a “yellow dwarf” and there are many stars with masses less than the Sun called “red dwarfs”. Very low mass objects that do not have enough material to ignite nuclear fusion in the center are called “brown dwarfs”. The color of a star is an indication of the temperature at its surface. Very hot objects emit more blue-white light, while cooler objects emit more red light.
