A 116 Year Record of Mass Transfer in R Arae
Phillip A. Reed
TL;DR
This study analyzes 116 years of observational data on the eclipsing binary R Arae to determine its average mass transfer rate, providing an updated ephemeris and insights into its long-term evolution.
Contribution
It presents the first long-term mass transfer rate estimate for R Arae by combining new and archival photometric data over 116 years.
Findings
Average mass transfer rate determined from 116 years of data
Updated ephemeris for R Arae provided
Long-term evolution insights for the binary system
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.
