When Homer Nods – reconciling our period analysis of V883 Sco with history

Presented by Tom Richards, Neil Butterworth, Mark Blackford

V883 Sco is an eclipsing binary with a V magnitude of 7.3 and widely quoted period of 1.29484 d. Observations at Townsville Observatory by NDB over three observing seasons showed this period was very wrong. MDB analysed NDB’s data and derived an incommensurate period of 4.3412 d, which moreover fitted with analysis of INTEGRAL-OMC and ASAS3 data. This paper will present the original photometric data and provide an analysis method showing how that data, though apparently supporting the original period, are consistent with and support our period.
