The Seager
equation treats only the red dwarfs, that is, a
certain set of stars, the socalled Mstars. One
can extend the consideration here and also refer
to other sets of stars, e.g. On the Gstars the
sunlike stars.
The Seager equation is then compatible with
Equation System 6.3.3 and can be completely
replaced by the relationships found in Chapters
17. 
N* = N_{s}
= A·F_{s} according to
Equation 1.4.1, for the number of G stars (sunlike
stars) present in the galaxy with F_{s
}= 7:25 and A = 100300 billion
stars.
f_{Q} Gstars
do not throw gamma rays into space, so all stars are
observable, ie f_{Q} =1. The factor can therefore
be dispensed with.
f_{HZ}
= F_{ph} = F_{p}·F_{h
}is the proportion of those G stars, which
have a planet first, and secondly it is in a habitable
zone. F_{p} =
201:14,000 and F_{h}
= 10:603.
f_{O} =
F_{k} quantifies the
proportion of those planets which visibly travel past the
star for the Kepler telescope. According to Chapter 1.2,
the probability of such a transit is 0.47 % so F_{k}
= 0.004,7.
f_{L} =
F_{L} is the fraction
of planets with life, with F_{L}
= 1:9.
f_{S} stands
for an intelligence which leaves a measurable
biosignature in the atmosphere, ie a technological
civilization, with f_{S}
= F_{i}·F_{z}
= 1:14 · 1:7,943 = 1:111.203
The entire Seager equation can then be applied to the set
of solarlike star systems in the galaxy observed with
the Kepler telescope (or equivalent). All the probability
factors of the Seagerequation are completely replaceable
by the factors from the equation system 6.3.3. The
transformed Seager equation for G stars is then:
10.3.1 Equation 
N = A · F_{s}
· F_{p }·
F_{h}
· F_{k }·
F_{L }·
F_{i}
· F_{z} 
According to definition 1.7.1 is F_{sph }= F_{s}
· F_{p} · F_{h} = 1:15,000
According to definition 6.2.2 is: F_{Liz} = F_{L}
· F_{i} · F_{z} = 1:987
Equation 10.3.1 can thus also be written as transformed
SeagerEquation:
10.3.2 Equation 
N = A · F_{sph}
· F_{k }·
F_{Liz} 
Substituting
all the values into equation 10.3.2:
N = (100300)·10^{9} · 1:15,000 · 0.004,7 ·
1:1001
N = 32 – 94 technological civilizations
Comparison of special basic model
Equivalent and thus comparable to the
transformed Seager equation is equation 6.3.3 from the
Special Basic Model. According to theorem 6.4.1 of the
Special Basic Model, there are probably 10  290
technological civilizations, on "Earth 2" in
solarlike systems, in our galaxy.
The Drake Seager window is well located in the lower part
of the basic model window. The Drakecorrected Special
Basic Model 9.8.2 delivers 22  199
"Earths 2" with technological civilizations.
The Seager_window is well located in the lower part of
the Drake window.
10.3.3 Theorem 
The special basic model and
the transformed Seager equation represent two
mutually equivalent approaches. 
In the Seager approach, earthsimilarity plays no
role and only technological civilizations, on habitable
planets in the galaxy, are asked.
This model can also be transferred to other star sets and
observation devices. If you omit the factor F_{z},
then you can apply equation 10.3.2 to intelligent
species. If you omit the factor F_{i}, then
equation 10.3.2 can also be applied to animate planets.
