A neutron star and a white dwarf have been found orbiting eachother with a period of 26 minutes. If their masses are typical,what is their average separation? Compare the separation with theradius of the sun, 7 ✕ 105 km. (Hints: Use theversion of Kepler's third law for binary stars,
MA +MB =
;
make sure you express quantities in units of AU, solar masses,and years. Assume the mass of the neutron star is 2.0 solar massesand the mass of the white dwarf is 0.7 solar masses.)
Ans:
______________ solar radius
