The concept of the “lifetime” of a population of binaries is applicable only to those of low binding energy, i.e. wide pairs. Of several possible methods of estimating a lifetime, that based on the average change in binding energy due to non-disruptive encounters appears to be the best.

Resumen

Resumen

EI concepto de tiempo característico de una población de estrellas binarias se aplica solamente a aquellas de poca energía de amarre, esto es, a binarias separadas. Se encontró que de entre varios posibles métodos para estimar el tiempo característico, el mejor es el que se basa en el cambio promedio de la energía de amarre debido a encuentros que no rompen el sistema.
