Citizen ASAS-SN: Citizen Science with The All-Sky Automated Survey for SuperNovae (ASAS-SN)

Abstract

We present "Citizen ASAS-SN", a citizen science project hosted on the Zooniverse platform which utilizes data from the All-Sky Automated Survey for SuperNovae (ASAS-SN). Volunteers are presented with ASAS-SN g-band light curves of variable star candidates. The classification workflow allows volunteers to classify these sources into major variable groups, while also allowing for the identification of unique variable stars for additional follow-up.

ASASSN-21co: A detached eclipsing binary with an 11.9 year period

“…Although primarily designed for transient phenomena, the V -band observations have been used to classify ∼ 426, 000 variables, including ∼ 150, 000 eclipsing binaries (Jayasinghe et al 2019(Jayasinghe et al , 2021. The ongoing ASAS-SN Citizen Science campaign (Christy et al 2021) has also already identified a host of new variable stars in the g-band data.…”
