The analysis of the Class 1 star N 11-95 (LMC), which has an observed vsin(i) of 267 km s-1. The blue solid line shows the calculated surface nitrogen abundance as function of the fractional main sequence life time τ of an LMC star with the mass of N 11-95 and assuming a rotational velocity of 267 km s-1. The red dotted line indicates the measured surface nitrogen abundance of N 11-95. The black vertical arrow gives the derived upper limit on τ, i.e. τ < 0.43.
