Rowan Introduction to AstronomyActivity #8: Stellar RemnantsName: _______________________________________________Score: _______________________________1. White dwarfs and neutron stars. A spectral type B7 star like Alcyone in the open cluster Pleiades will end its stellar life byejecting most of its mass into a planetary nebula. The remaining mass (the stellar core or corpse) will collapse into a white dwarf.A white dwarf is a member of a class of objects called compact objects that also includes neutron stars and black holes.Compact objects are incredibly dense. For white dwarfs, the outer electrons of the atoms that makeup the star’s matter arepacked closely as a result of electron degeneracy. For neutron stars, under the immense pressure of gravity, the electrons havecombined with the protons to form neutrons, leaving the neutrons in a state known as neutron degeneracy.Given that the density of a white dwarf is 109kg/m3and that the density of a neutron star is 1017kg/m3, determine the weights, intons, of:(a)1 cubic centimeter (1 cm3
