Capitalizing on contemporaneous color photometry

[christinahedges]

Contemporaneous color photometry can unlock the potential of studies of stellar variability and dusty disks, as well as enabling the identification of exoplanet false positives. During K2 Campaigns 16 and 17, Keplers observations were complemented by contemporaneous PanSTARRS1 photometry from the ground (Dotson et al. 2018). PanSTARRS surveyed Keplers entire field of view for 56 nights in four filters (g, r, i, z). The primary motivation behind obtaining these data was to identify supernovae in the field in time for contemporaneous follow-up observations, but the high-cadence color data are expected to enable a range of additional studies. The data were made public in September 2018. High-cadence contemporaneous color photometry was also obtained during K2 Campaign 9 (Henderson et al. 2016; Zang et al. 2018). To date, these data have been under-utilized in conjunction with K2 observations.
