Identification of Young Stellar Variables with KELT for K2 I: Campaign 13 Taurus [SSA]

One of the most well-studied young stellar associations, Taurus-Auriga, will be observed by the extended Kepler mission, K2, in the spring of 2017. K2 Campaign 13 (C13) will be a unique opportunity to study many stars in this young association at high photometric precision and cadence. Using observations from the Kilodegree Extremely Little Telescope (KELT) survey, we identify “dippers”, stochastic variables, and periodic variables among K2 C13 target stars. This release of KELT data (lightcurve data in e-tables) provides the community with long-baseline observations to assist in the understanding of the more exotic variables in the association. Transient-like phenomena on timescales of months to years are known characteristics of young stellar objects, making contextual pre- and post-K2 observations critical to understanding the underlying processes. We are providing a comprehensive set of KELT light curves for known Taurus-Auriga stars in K2 C13. The combined data sets from K2 and KELT permit a broad array of investigations related to star formation, stellar variability, and protoplanetary environments.
