Using the
hydrostatic law
for a uniform
density
star gives the stellar pressure as a function of radius
r
as
(1)
where
is the
density
,
G
is the
gravitational constant
,and
R
is the stellar radius.Applying the
ideal gas law
at the star's center then gives
(2)
where
m
is the molecular mass and
k
is
Boltzmann's constant
. Therefore, assuming only hydrostatic equilibrium (i.e., ignoring thermonuclear fusion), the temperature at the center of the star is
(3)
where
M
is the mass of the star.
