ASAS-SN Identification of FY Sct as a Detached Eclipsing Binary System with a 2.6 Years Period

Abstrakt

The All-Sky Automated Survey for SuperNovae (ASAS-SN, Shappee et al. 2014; Kochanek et al. 2017) has monitored the entire visible sky to a depth of ~17 mag in the V-band since 2014. ASAS-SN data is well suited for the discovery and study of variable stars (Jayasinghe et al. 2018a; Shields et al. 2018).

In Jayasinghe et al. (2018b), we have uniformly analyzed the ASAS-SN light curves of ~412,000 known variables in the VSX catalog (Watson et al. 2006), providing homogeneously classified samples of variable groups for further study. Here we report the identification of a long period detached eclipsing binary system.
