R Arae
R Arae is an Algol-type eclipsing binary in the constellation Ara. Located approximately distant,〔 it normally shines at magnitude 6.17, but during eclipses can fall as low as magnitude 7.32. It has been suggested by multiple studies that mass transfer is occurring between the two stars of this system, and the period of eclipses seems to be increasing over time.〔 ==References==
