During the last five years there have been spectacular advances in observational astrophysics. The study of supernovas has reached maturity and the detection of gravitational waves caused by the fusion of a binary system with two black holes or two neutron stars is a fundamental advance of Science. Now that we are sure that these systems exist, we can ask ourselves how they are formed. There are many models that try to explain them using what we know about the evolution of massive stars, but they have a hard time reproducing the right number of suitable systems. There are too many uncertainties in our knowledge of the life of massive stars, which resembles a disassembled puzzle with missing pieces. Our research attempts to provide a new and different view of the problem, finding the site of the elements by observing large samples of massive stars and determining their astrophysical parameters. In this way, we build the observational landscape in which the creators of models have to fit their proposals.
