hi(adsbygoogle = window.adsbygoogle || []).push({});

can the bolometric correction be calculated if all i know of a cepheid variables properties are its period? for example, if the cepheid variable has a period of 3 days i can use a period-luminosity relationship to calculate the luminosity, from here i can then calculate the bolometric magnitude. my question really is this, can i then calculate the bolometric correction required to find the absolute visual magnitude? or is there an easier way to get to the absolute visual magnitude from just the information given.

hopefully some one can point me in the right direction, thanks

(this is a question that has come up in one of the books i am reading, so if it is in the wrong forum i appologies)
