We present the first results of our adaptive optics survey of 200 (mainly) A-type stars in the nearby OB association Sco OB2, which we will use, together with literature data and detailed simulations of young star clusters, to determine the primordial binary population.

Resumen

Resumen

Presentamos los primeros resultados de nuestro sondeo con óptica adaptativa de 200 estrellas principalmente de tipo A en la asociación OB cercana Sco OB2. Estos resultados, junto con datos de la literatura y simulaciones detalladas de cúmulos jóvenes, serán utilizados para determinar la población primordial de binarias.
