Why would a neutron star have such a strong magnetic field?

If neutron stars are hot, why aren't they very luminous?

Why is there an upper limit to the mass of neutron stars?

Calculate the gravitational redshift of radiation of wavelength 550 nm that is emitted from a neutron star having a mass of 5.8 x 1030 kg and a radius of 10 km. Assume that the radiation is being detected far from the neutron star.

Why are emission nebulae red ?

What evidence can you cite that pulsars are neutron stars?

RR Lyrae stars have essentially the same luminosity curve, with periods of up to 1 day.     False     True   47

What are the main products of the fusion reactions that take place in low mass main sequence stars?

If a circular accretion disk around a 1.4 M, neutron star has a radius of 1.00 x 105 km as measured from the center of the neutron star to the edge of the disk, what is the orbital velocity (in km/s) of a gas particle located at its outer edge? (The mass of the Sun is GM 1.99 x 1030 kg. Hint: Use the circular orbit velocity formula, V, = ; make sure to express quantities in units of meters, kilograms, and seconds.) km/s

How can a neutron star in a binary system generate X-rays?
