We discuss theoretical aspects of binary and multiple star formation, focusing on their formation in stellar clusters. First, we review individual processes that may occur during the formation of binary and multiple stars: fragmentation, accretion, interactions with circumstellar discs, and dynamical interactions. We then discuss the results from a recent large-scale hydrodynamical calculation of cluster formation in which all of these processes occur simultaneously, examining the formation mechanisms and resulting properties of the binary and multiple stars in this cluster.

Resumen

Resumen

Discutimos aspectos teóricos de la formación de estrellas dobles y múltiples, particularmente en cúmulos estelares. En primer lugar, revisamos los procesos individuales que pueden ocurrir durante la formación de estrellas dobles y múltiples: fragmentación, acreción, interacciones con discos circunestelares e interacciones dinámicas. En segundo, discutimos los resultados recientes del cálculo hidrodinámico a gran escala de la formaciónde un cúmulo, en el cual todos estos procesos ocurren simultáneamente, y examinamos los mecanismos de formación y las propiedadesresultantes de las binarias y múltiples en el cúmulo.
