Unformatted text preview: So, angular diameter is about 1/1000 arc-minute. 5./ Use Wien's Law relating temperature to maximum wavelength: wavelength max = 3,000,000 / T , where T is temperature in Kelvin. For T = 1,000,000 K, w-max = 3,000,000 / T = 3,000,000 / 1,000,000 7./ P 2 = a 3 / (M 1 + M 2 ) P = period of rotation in years a = distance between the objects in Aus M 1 and M 2 = mass of the first and second objects (respectively) in solar masses Average neutron star mass = 1.75 solar masses P = 13.1 / 365 = 0.03589 years a = 0.3037 AU...
