Tesis doctoral inédita leída en la Universidad Autónoma de Madrid, Facultad de Ciencias, Departamento de Física Teórica. Fecha de lectura: 21-09-2009Resumen La regi´on de formaci´on estelar Orionis, situada en la cabeza de Ori´on, forma parte de la nube molecular de Ori´on pero situado a unos 15 grados al Norte del centro del complejo (con una declinaci´on ∼10o). La estrella Ori es el miembro m´as brillante del c´umulo central Collinder 69. ´Este es un c´umulo abierto compacto y bien definido. Otras dos asociaciones algo menores se encuentran situadas cerca de Collinder 69 y est´an asociados a las nubes moleculares Barnard 30 y Barnard 35. En el infrarrojo medio y a 21 cm, Ori marca el centro de burbuja circular de cuatro grad...
