A neutron star has a density equal to that of the nuclear matter. Assuming the staar to be spherical, find the radius of a neutron star whose mass is `4.0xx10^30`kg (twice the mass of the sun ).

Text Solution

Verified by Experts

The correct Answer is:
`r_(1)=[(4xx10^(30))/(3xx10^(17))xx(1)/(4pi)]^(1//3)= 14.71 km`
(ii) `r_(2)=[(6xx10^(24))/(3xx10^(17))xx(3)/(4pi)]^(1//3)=168.4m`

A neutron starj has a density equal to theat of nuclear matter (~= 2.8xx10^(17) kg//m^3). Assuming the star to be spherical, find the radius of the neutron star whose mass is 4.0xx10^(30)kg.

Density of a neutron star is 2.7xx10^(17)kg m^(-3) . Assume the star to be spherical, calculate the radius of the neutron star if its mass is twice the mass of the sun. Take mass of the sun =2.0xx10^(30)kg

Consider a white dwarf and a nutron star beach of one solar mass. The radius of the white dwarf is same as that of the eartyh (=6400km) and the radius of the neutron star is 10 km. Determine the densities of the two types of the stars. Take mass of the sun =2.0xx10^(30) kg.

The Doppler effect has made it possible to discover the doubles stars which are so distance that their resolution by means of a telescope is impossible. The spectral lines of such stars periodically become doublets indicating that the radiations does come two stars revolving about their centre of mass. Assuming the masses of the two stars to be equal, find the distance between them and their masses if the maximum splitting of the spectral lines is equal to (Delta lambda//lambda)_(m) = 1.2.10^(-4) and occurs every tau = 30 days.

The luminousity of a star is 10,000 times that of the sun and its surface temperature is 3000K . Assuming the surface of temperature of the sun to be 6000K , compare the radius of the star with that of the sun.

The small dense stars rotate about their common centre of mass as a binary system, each with a period of 1 year. One star has mass double than that of the other, while mass of the lighter star is one-third the mass of the Sun. The distance between the two stars is r and the distance of the earth from the Sun is R , find the relation between r and R .

The Sun, which is 2.2 xx 10^20 m from the center of the Milky Way galaxy, revolves around that center once every 2.5 xx 10^8 years. Assuming each star in the Galaxy has a mass equal to the Sun's mass of 2.0 xx 10^30 kg, the stars are distributed uniformly in a sphere about the galactic center, and the Sun is at the edge of that sphere, estimate the number of stars in the Galaxy.
