Lesson plan
Star count
Star counts are census counts of stars and the statistical and geometrical methods used to correct the corresponding data for bias. The surveys are most often made of nearby stars in the Milky Way galaxy. The total number of stars counted in a particular direction depends on the location and density of stars, the luminosity function, and the absorption. Star count programs can therefore collect data that bounds or determines these values. One of the interests of astronomy is to determine how many stars there are of each of several types that stars can be categorized into, and how these stars are distributed in space.
