Life Cycle of a Star
... The color of a star is dependant on its temperature. Astronomers measure the temperature of each star by its outer most layer or its photosphere. O stars, which are the hottest of the seven categories, are blue in color. M stars, which are the coolest, are red. Within the range of this spectrum, the ...

The Mass-Luminosity Relationship and Stellar Lifetimes
... • Our intuition would seem to say that since big stars have a lot more fuel to consume, they should last a lot longer than smaller stars. • It doesn’t work this way, however. If the luminosity of a star increases with the 4th power of the mass, that means that the star is producing energy and using ...

Star catalogue
A star catalogue, or star catalog, is an astronomical catalogue that lists stars. In astronomy, many stars are referred to simply by catalogue numbers. There are a great many different star catalogues which have been produced for different purposes over the years, and this article covers only some of the more frequently quoted ones. Star catalogues were compiled by many different ancient peoples, including the Babylonians, Greeks, Chinese, Persians, and Arabs. Most modern catalogues are available in electronic format and can be freely downloaded from NASA's Astronomical Data Center.Completeness and accuracy is described by the weakest apparent magnitude V (largest number) and the accuracy of the positions.
