The classical theories of double star formation are briefly reviewed in relation to the origin of multiple stars. Modern observations in the infrared are discussed and their relevance as clues to the process of multiple star formation is stressed. These observations, together with dynamical considerations and data on the statistics of trapezia and hierarchical multiple systems, support the view that multiple stars, in general, are born as trapezia, that is, as independent condensations.

Resumen

Resumen

Se hace una breve reseña de las teorías clásicas para explicar el origen de las estrellas dobles, y de su relación con el origen de los sistemas múltiples. Se discuten las observaciones que recientemente se han hecho en el infrarrojo, enfatizado su importancia para el entendimiento del proceso de formación de las estrellas múltiples. Estas observaciones, junto con consideraciones dinámicas y datos estadísticos sobre trapecios y sistemas múltiples jerárquicos, apoyan la idea de que las estrellas múltiples, en general, se originan como trapecios, es decir, como condensaciones independientes.
