Summary
The problem of the propagation of disturbances in the inside of stars is discussed in its general aspects and as regards its solubility by means of electronic computers. The problem of the stability of the numerical processes is therefore studied, and, after bringing out the need to use stellar models in analytical form in order to find the convergence of the solutions obtained, the results are applied to generalized Koche’s models so selected as to represent very closely particular models of stars already calculated with a considerable degree of physical accuracy. There will be further papers on the numerical results obtained.
Riassunto
Si discute il problema della propagazione di perturbazioni nell’interno delle stelle nel suo aspetto generale e in quello relativo alla sua soluzione mediante calcolatori elettronici. Si studia il problema della stabilità numerica dei procedimenti di calcolo adottati e, sottolineata a tale proposito l’opportunità dell’uso di modelli stellari analitici, si applicano questi procedimenti a modelli di Roche generalizzati, scelti in modo da adattarsi con sufficiente accuratezza ad alcuni modelli stellari già calcolati con buona aderenza alla realtà fisica. Successivamente si riportano i risultati numerici ottenuti.
