On the HR diagram provided draw the path for a star that is the mass of our sun as it runs out of hydrogen becomes a giant and makes it to a white dwarf. On the diagram describe the different steps. Start here the star runs out of H in core expands contracts and begins to fuse HE with H shell...continues to C?O.....eventually ends as white dwarf. On the same HR diagram draw a similar path describing the fusion processes for a star that is 15 tines the mass of sun. It should end as a supernova.
