Note: The stars that fall in the middle of the star types list, its colour is white, that is, the combination of all colours. They are usually produced by stars with less than 20 solar masses, although a more massive star may produce a neutron star in certain cases. O stars are the hottest, with temperatures from about 20,000K up to more than 100,000K. A farmer has 19 sheep All but 7 die How many are left? Red stars The red dwarf stars are considered the smallest stars known, and representative of the smallest star possible. The hotter a star is, the shorter its wavelength of light. A star's color is caused by the type of gases its made up of and the. To understand what causes different-colored flames, its important to understand the science behind visible light and fire. Mass increases the central temperature, resulting in a significant increase in luminosity. This new data will enable us to study these stars in a variety of new ways that were previously impossible due to their extreme faintness; many of these stars have never been studied in detail due to their extreme light levels, but with this new data, we will be able to do so. The cooler a star is, the less energy it emits, and the redder its color. Stars exist in a range of colors: red, orange, yellow, green, white and blue with red being the coolest and blue being the hottest. When ordered by temperature and when duplicate classes were removed, the spectral types of stars followed, in order of decreasing temperature with colors ranging from blue to red, the sequence O, B, A, F, G, K and M. Based on the color wheel, we notice that some colors or their shades give us a feeling of warmth or coolness.
