In 2013, MIT astrophysicist Sara Seager introduced what is now called the Seager Equation (Refs. [20,21]): it expresses the number N of exoplanets with detectable signs of life as the product of six factors: Ns=the number of stars observed, fQ=the fraction of stars that are quiet, fHZ=the fraction of stars with rocky planets in the Habitable Zone, fO=the fraction of those planets that can be observed, fL=the fraction that have life, fS=the fraction on which life produces a detectable signature gas. This we call the "classical Seager equation".
