  1. Question, though not directly related to this week’s hangout (which was great, BTW!)

    Cepheid Variables – OK, so I understand the whole thing about Henrietta Swan Levitt cataloging LMC variables and correlating variable period with overall luminosity. What I can’t find or figure out is WHY a cepheid’s period is related to its luminosity. I can’t wrap my head around it. Why does the pulsation period have anything at all to do with the star’s overall maximum brightness? I’m clearly missing some basic information.
