11 – Equivalence of Considerations

11.1 - Equivalence

As the transformation shows overall, the Drake-Seager equation, after adaptation to sun-like stars, can be regarded as equivalent to the Special Basic Model 6.3.3. For this to be exactly the case, both equations must be equivalent to each other.

According to the basic model: Nze = A Fsph Fgae FLiz
The Drake-Seager approach provides: N = A Fsph Fk FLiz

It must then apply:

Nze = N
AFsphFgaeFLiz = AFsphFkFLiz
Fgae = Fk

If Fgae = Fg Fa Fe is used according to definition 3.1.3, then an assessment can be made for Fe. It turns out:

Fgae = FgFaFe = Fk

converting the equation to Fe:

11.1.1 Equation Equation

Substituting the values in Equation 11.1.1 yields:

Fe = 0.004,7 / (1,212:3,286 51:130)
Fe = 0.032,481 = 1:31

This is only three times greater than the previous minimum value, and can be used as a new upper limit. With the new barriers, some theorems formulated so far can be differentiated somewhat.
