Resumen:
We obtained medium resolution $K$-band spectra for two B[e] supergiants and one yellow hypergiant (YHG) in the Large Magellanic Cloud (LMC) and found that the spectra of all three stars show enhanced 13CO band emission, in agreement with theoretical predictions for evolved stars. Our preliminary results for the two B[e]SGs seem to indicate that one is a pre-RSG star while the other is in a post-RSG phase.
