We examine the correlation of projected rotational velocities in binary systems. It is an extension of previous work (Steinitz and Pyper, 1970; Levato, 1974). An enlarged data basis and new tests enable us to conclude that there is indeed correlation between the projected rotational velocities of components of binaries. In fact we suggest that spins are already correlated.

Resumen

Resumen

Examinamos la correlación entre las velocidades de rotación proyectadas en sistemas binarios. Este estudio es una extensión de un trabajo previo (Steinitz y Pyper, 1970; Levato, 1974). Una base de datos más amplia y nuevas pruebas nos permiten concluir que, en efecto, existe una correlación entre las velocidades de rotación proyectadas de las binarias. Sugerimos, de hecho, que los espines están correlacionados.
