Abstract: The optical spectrum of the star SMSS J031300.36−670839.3 shows no evidence of iron; this, together with comparisons of the star’s observed element abundance pattern with those of models, means that SMSS J031300.36−670839.3 must have been seeded with material from a single supernova with an original mass about 60 times that of the Sun.
