The speed of sound at the critical condition can also be a good reference velocity. The speed of sound at that velocity is
\[
c^{*} = \sqrt{k\,R\,T^{*}}
\label{shock:eq:starSpeedSound}
\]
In the same manner, an additional Mach number can be defined as
\[
M^{*} = \dfrac{U }{ c^{*}}
\label{shock:eq:starMach}
\]
