Repeating Outbursts from the Young Stellar Object Gaia23bab (=SPICY 97589)
Abstract
The light curve of Gaia23bab (=SPICY 97589) shows two significant (ΔG > 2 mag) brightening events, one in 2017 and an ongoing event starting in 2022. The source's quiescent spectral energy distribution indicates an embedded (A V > 5 mag) pre-main-sequence star, with optical accretion emission and mid-infrared disk emission. This characterization is supported by the source's membership in an embedded cluster in the star-forming cloud DOBASHI 1604 at a distance of 900 ± 45 pc. Thus, the brightening events are probable accretion outbursts, likely of EX Lup-type.
