A relativistic effect in pulsating fluid spheres

  • F. de Felice


The purpose of this note is to describe a relativistic effect of energy accumulation which arises when spherically symmetric configurations are enclosed in a sufficiently small volume. Conditions for a release of this energy are analysed and possible physical applications of this effect are suggested.

Релятивстский зффект в пульсируюшей жидкой сфере


Цель зтой статьи состоит в описании релятивистского зффекта накопления знергии, которое воэникает, когда сферически симметричные конфигурации эаключены в достаточно малый общем. Аналиэируются условия выделения зтой знергии, и предлагаются воэможные фиэические применения зтого зффекта.


Scopo di questo articolo è descrivere un effetto relativistico di accumulazione di energia che si manifesta quando configurazioni a simmetria sferica sono contenute in volumi sufficientemente piccoli. Si esaminano le condizioni in cui questa energia viene liberata come radiazione e si suggeriscono alcune possibili applicazioni fisiche.
