A white dwarf in a binary system has a radius of 7000 km and a mass equal (minus an infinitesimal amount) to the Chandrasekhar limit of 1.4M sun. The companion transfers an infinitesimal amount of mass to the white dwarf which is enough to send it over the Chandrasekhar limit and it collapses to a neutron star with a radius of 14 km. Calculate the amount of gravitational potential energy released. NOTE: we can assume that the mass of the neutron star once is triggered and the mass of the WD are both equal to the Chandrasekhar mass in this case.
