A neutron star is the remnant left after certain supernovae (explosions of giant stars). Typically, neutron stars are about 18 km in diameter and have around the same mass as our sun. What is a typical neutron star density in g/cm^3?

Answer:

[tex]Density=6.51*10^{14}g/cm^{3[/tex]

Explanation:

Sun mass:

Ms=1.989 × 10^30 kg

Neutron star has the same mass.

Radius Neutron:

R=9Km (because diameter is 18Km)

R=9*10^3m

Density neutron star:

[tex]D=Mn/Vol=Ms/(4/3*\pi*R^3)=1.989*10^{30} /(4/3*\pi*(9*10^{3})^{3})=6.51*10^{17}kg/m^{3}[/tex]

[tex]D=6.51*10^{17}kg/m^{3}*(1000g/1Kg)*(1m^{3}/1000000cm^{3})=6.51*10^{14}g/cm^{3[/tex]
