In an X-ray burster, the surface of a neutron star 10 km in radius is heated to a temperature of 3 x 107K. (a) Determine the wavelength of maximum emission of the heated surface ( which you may treat as a blackbody ). In what part of the electromagnetic spectrum does this lie? (See Figure.) (b) Find the luminosity of the heated neutron star. Give your answer in watts and in terms of the luminosity of the Sun (the luminosity of Sun is 3.86 x 1026W). How does this compare with the peak luminosity of a nova? Of a Type Ia supernova?
