during helium burning, carbon and oxygen will accumulate in the core and heavy mass loss continues. this eventually leads to the development of a wc spectrum, although at lmc metallicity a star is expected to spend most of the helium burning phase with a wn spectrum. towards the end of helium burning, core temperature increase and mass loss cause an increase in both luminosity and temperature, with the spectral type becoming wo. several hundred thousand years will be spent fusing helium, but the final stages of heavier element burning take no more than a few thousand years. r136a1 will eventually shrink to a little over , with just of helium left surrounding the core.
