Abstract

A new method of integration has been performed and applied to the computation of the cooling sequence of a 0.15M white dwarf consisting of helium. The results are discussed and compared with the previous ones obtained by other authors.

Riassunto

E' stato elaborato un nuovo metodo di integrazione numerica, ed applicato al calcolo della sequenza evolutiva di raffreddamento di una nana bianca di puro elio di 0.15M. I risultati vengono discussi e confrontati con i precedenti modelli ottenuti da altri autori.
