Abstract The object of this investigation is to determine some gross effects of mass loss on stellar evolution A star of an initial mass of 15 Mo is evolved from the main sequence, through core hydrogen burning, hydrogen exhaustion, shell hydrogen burning to past the onset of core helium burning The star is continually losing mass at a rate ranging from 5 6 X 10- Mo/yr to 1.7 x 10- Mo/yr. The mass of the last computed model is 1168 Mo. The early evolution is compared to that of a 15 Mo star evolving at constant mass. It is concluded that extensive mass loss (1) broadens the main sequence near the turnoff point; (2) reduces the ages of clusters determined by fitting with conventional evolutionary tracks; and (3) that an upper limit exists to the amount of mass a star can lose if it is to become a red supergiant.
