WebbThe period-luminosity relationship for type 2 Cepheids is given by: log L = a * log P + b, where L is the luminosity of the star, P is its period, and a and b are constants. For type 2 Cepheids, the values of a and b are approximate: a = 1.5 b = -3.3 Using these values, we can solve for the luminosity of the type 2 Cepheid: log L = 1.5 * log 30 ... http://scihi.org/henrietta-swan-leavitt-light-cepheids/ WebbWhen properly callibrated, this leads to a "period-luminosity relationship," and if we know the star's intrinsic luminosity, we can infer its distance by observing its apparent brightness.
