Abstract

We report the existence and characteristics of an IR counterpart to IC 10 X-2, a compact object-supergiant binary in the galaxy IC 10. Previous optical and X-ray studies argue that the system resembles a Supergiant Fast X-ray Transient: a large-amplitude (~100), short-duration (hours to weeks) X-ray outburst. We discovered mid-IR variability concurrent with its X-ray outburst. We track its mid-IR variability over seven epochs in 2004-2016 and present near-IR imaging and spectroscopy taken at Palomar Observatory in July 2016. We also model IC 10 X-2 pre- and post-eruption, shedding light on the nature of the supergiant star in the binary system.
