Question 1

Essay

With the Hubble Space Telescope,you discover a Cepheid variable star in a nearby galaxy that has a period of 30 days.If nearby Cepheids follow a period-luminosity relationship that says the luminosity of the star is With the Hubble Space Telescope,you discover a Cepheid variable star in a nearby galaxy that has a period of 30 days.If nearby Cepheids follow a period-luminosity relationship that says the luminosity of the star is ,then what is this Cepheid's luminosity and absolute magnitude? Recall that the Sun's absolute magnitude is .If the apparent magnitude of the Cepheid is 25,what is this galaxy's distance in Mpc? ,then what is this Cepheid's luminosity and absolute magnitude?
