Critical reading of some papers related to the Bibracte basin
2021
Since its discovery in 1987, the monumental basin of Bibracte questions archeologists because of its atypical orientation that was thought not to follow the way on which it lies. We study 4 archeoastronomical papers dealing with the orientation of the short and long axes on the sun rise at winter solstice or on peculiar stars and we discuss the validity of these hypotheses.
Can we ascertain that an archeological site contains intentional stellar alignments?
2021
We study the different parameters that support the presence of intentional stellar alignments on an archaeological site. We develop a rigorous criterion to quantify the probability of fortuitous orientation on a starrise or a starset. We show that the magnitude of the considered stars and the precision of the angular measurements are the two preponderant parameters. Our study aims at establishing the basis of reliable methods for archaeoastronomy.
