Pulsations are generally split into: radial, where the entire star expands and shrinks as a whole; and non-radial, where one part of the star expands while another part shrinks. A giant star is a star with substantially larger radius and luminosity than a main-sequence (or dwarf) star of the same surface temperature. The system of 283 asterisms under Three Enclosures and Twenty-eight Mansions was established by Chen Zhuo of the Three Kingdoms period, who Pulsating stars swell and shrink, affecting their brightness and spectrum. Very old star names originated among people who lived in the Arabian Peninsula more than a thousand years ago, before the rise of Islam.However, some Arabic language star names sprang up later in history, as translations of ancient Greek language descriptions..

In order of decreasing temperature, the seven main spectral classes in the Morgan-Keenan classification system are: O, B, A, F, G, K, and M.
