Resumen:
Cepheus A is one of the closest (725 pc distance) high-mass star-forming regions. At the center of a high-density molecular core seen in ammonia lines, within a ?20 " (?15, 000 AU) radius, there is a cluster of sixteen compact radio continuum sources observed at centimeter wavelengths, some of them associated with phenomena such as Herbig-Haro (HH) objects, molecular outflows, jets, disks, masers, and strong magnetic fields, all of which are signatures of the first steps of the evolution of very young stars. In this contribution, we will review some of the past and most recent observations of Cepheus A, a laboratory for testing and opening new puzzling questions related to the early stellar evolution. © 2007 Springer.
