A 116 Year Record of Mass Transfer in R Arae
arXiv:1102.3230
Abstract
This is a period study of the bright interacting southern eclipsing binary star R Arae. New photometric data are combined with archival data to determine R Ara's average mass transfer rate over the past 116 years through the analysis of the resulting ephemeris curve. An updated ephemeris is given.
