S Coronae Australis (S CrA), is a young binary star system estimated to be around 2 million years old located in the constellation Corona Australis. It is composed of a G-type main sequence star that is about as luminous as and just over twice as massive as the Sun, and a smaller K-type main sequence star that has around 50-60% of the Sun's luminosity and 1.3 times its mass. Both stars are T Tauri stars and both show evidence of having circumstellar disks. The system is around 140 parsecs distant.

- S Coronae Australis är en eruptiv variabel av T Tauri-typ (INT) i stjärnbilden Södra kronan. Stjärnan varierar mellan visuell magnitud +10,49 och 13,2 utan någon fastställd periodicitet. (sv)
- 南冕座S(S Coronae Australis,S CrA),是一个年轻的联星系统,有大约200万年的历史,位于南冕座。它由一颗G-型主序星和一颗稍小的K-型主序星构成,前者亮度与太阳一样,质量是太阳质量的两倍,后者亮度是太阳的大约50-60%,质量是太阳的1.3倍。两颗恒星都是金牛T星,并且按观测证据它们都有星周盘。该系统距离地球大约为140秒差距。 (zh)
