Neuron Stellar Cores

    Neutron Stellar Cores...

    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.

    [tex]v_s >= c[/tex]

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

    Acoustical Velocity:
    [tex]v_s = \sqrt{ \frac{B}{p_n}}[/tex]

    Acoustical Bulk Modulus:
    [tex]B = p_n v_s^2[/tex]

    [tex]p_n = \frac{3 \pi}{G T_n^2} = \frac{B}{v_s^2}[/tex]

    [tex]T_n = v_s \sqrt{ \frac{3 \pi}{GB}}[/tex]

    [tex]v_s >= c[/tex]

    [tex]T_n = c \sqrt{ \frac{3 \pi}{GB}}[/tex]

    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?
