Stato evolutivo delle stelle della Cintura di Orione ed implicazioni archeoastronomiche

TL;DR

This study assesses the evolutionary state of Orion Belt stars and finds their brightness was similar during pyramid construction, supporting the Orion Correlation Theory linking stars to Giza pyramids.

Contribution

It provides evidence that Orion Belt stars' brightness was unchanged since pyramid times, supporting the Orion Correlation Theory.

Findings

Orion Belt stars' brightness was similar during pyramid construction

Supports the Orion Correlation Theory

Implications for ancient Egyptian astronomy

Abstract

In the present work it is evaluated the evolutionary state of the Orion Belt stars, an asterism very important for the ancient Egyptians, finding that, when the pyramids were built, the brightness of the three stars of the Belt was practically the same as today. This not trivial result has important implications in the framework of the so-called Orion Correlation Theory, a controversial theory proposed by Bauval and Gilbert (1994), according to which a perfect coincidence would exist between the disposition of the three stars of the Orion Belt and that of the main Giza pyramids, so that the latter would represent the monumental reproduction on the ground of that important asterism. ---- Nel presente lavoro viene determinato lo stato evolutivo delle stelle della Cintura di Orione, ricavando che, all'epoca della costruzione delle piramidi, la luminosita' delle tre stelle della Cintura era di fatto uguale a quella odierna. Tale non banale risultato riveste una importanza fondamentale nell'ambito della verifica della controversa Teoria della Correlazione di Orione proposta da Bauval e Gilbert nel 1994, secondo la quale esisterebbe una perfetta coincidenza tra la disposizione delle tre stelle della Cintura e quella delle tre piramidi nella piana di Giza.
