What is the escape velocity (in km/s) from the surface of 1.1 M neutron star? (hint: Use the formula for the escape velocity Ve = 2GM/R ; make sure to express quantities in United of meters, kilograms, and seconds. Assume a neutron has a radius of 11 km and assume the mass of the sun is 1.99 x10^30 kg.)
1.1 M neutron Star = _________ km/s
3.0 neutron Star = __________ km/s
Calculate the Kepler speed grazing the surface of a) a white dwarf, b) a neutron star. Give your answers in terms of the speed of light. (Take RNS = 10 km, RWD = 10 000 km, and MWD = MNS = 1 Msun.)
A 1.5 M neutron star and a 0.7 M white dwarf have been found orbiting each other with a period of 10 minutes. What is their average separation? Convert your answer to units of the Sun's radius, which is 0.0047 AU.
