    1. The problem statement, all variables and given/known data

    i've heard of this equation from somewhere ....

    equation for periodic oscillation of brightness of stars.

    would like to know this astrophysics's name to see what else he's done

    2. Relevant equations


    3. The attempt at a solution

    he's also seen one of brightest solar flares or some periodic change or something....

    "periodic oscillation of brightness of stars."

    Sounds like Cepheid variables. A Wiki search turns up the name of Henrietta Swan Leavitt?
