Further empirical evidence for the non-linearity of the period—luminosity relations as seen in the Large Magellanic Cloud Cepheids
Abstract
Recent studies, using OGLE data for LMC Cepheids in the optical, strongly suggest that the period—luminosity (PL) relation for the Large Magellanic Cloud (LMC) Cepheids shows a break or non-linearity at a period of 10 d. In this paper we apply statistical tests, the chi-squared test and the F-test, to the Cepheid data from the MACHO project to test for a non-linearity of the V- and R-band PL relations at 10 d, and extend these tests to the …
