Fig. 2. The HR diagram for the stars in the field around SN 1987A: comparison with the theoretical ZAMS for different Z values and with isochrones for ages between 10 Myr and 6 Gyr (Brocato & Castellani 1993 and Cassisi et al. 1994)

Fig. 3. The spatial distributions of massive stars (M>6 M_sun; blue star symbols) and lower mass, PMS stars (M<3 M_sun; red squares) are shown superimposed on all measured stars. It is clear that the two distributions are remarkably different
