I watched a program in which a astrophysics professor suggested that in theoretical calculations, a Trans-Oppenheimer Neutron Stellar Core's acoustical velocity can exceed vacuum luminous velocity.

v_s >= c

Oppenheimer Neutron Stellar Density:
p_n = \frac{3 \pi}{G T_n^2}
Tn = Oppenheimer Neutron Star rotational period

Acoustical Velocity:
v_s = \sqrt{ \frac{B}{p_n}}

Acoustical Bulk Modulus:
B = p_n v_s^2

p_n = \frac{3 \pi}{G T_n^2} = \frac{B}{v_s^2}

T_n = v_s \sqrt{ \frac{3 \pi}{GB}}

v_s >= c

T_n = c \sqrt{ \frac{3 \pi}{GB}}

How was the Bulk Modulus calculated for a Trans-Oppenheimer Neutron Star?

Why is it theoretically unreasonable for trans-luminous acoustical velocities?

If trans-luminous acoustical velocities are theoretically possible, would such a result produce a Cherenkov Effect?
