K2 Campaign 13 (C13) is 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," aperiodic and periodic variables among K2 C13 target stars. This release of the KELT data provides the community with long-time 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 in the light curves of young stellar objects, making contextual pre- and post-K2 observations critical to understanding their underlying processes. We are providing a comprehensive set of the KELT light curves for known Taurus-Auriga stars in K2 C13. The combined data sets from K2 and KELT should permit a broad array of investigations related to star formation, stellar variability, and protoplanetary environments.2017ApJ...848...97Rhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/848/97CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toB/eso : ESO Science Archive Catalog (ESO, 1991-2018)II/246 : 2MASS All-Sky Catalog of Point Sources (Cutri+ 2003)V/133 : Kepler Input Catalog (Kepler Mission Team, 2009)II/328 : AllWISE Data Release (Cutri+ 2013)V/147 : The SDSS Photometric Catalogue, Release 12 (Alam+, 2015)I/337 : Gaia DR1 (Gaia Collaboration, 2016)IV/34 : K2 Ecliptic Plane Input Catalog (EPIC) (Huber+, 2017)I/345 : Gaia DR2 (Gaia Collaboration, 2018)J/A+A/299/89 : COYOTES II (Bouvier+, 1995)J/A+AS/120/267 : T Tauri stars UBrHalphaz photometry (Osterloh+ 1996)J/A+A/312/439 : New T Tauri stars in Taurus-Auriga (Wichmann+, 1996)J/A+A/349/619 : UBVRI light curves of AA Tau in 1995 (Bouvier+, 1999)J/AJ/117/2941 : Rotation periods of Orion PMS stars (Stassun+, 1999)J/A+A/379/564 : Vega & PMS stars UBVRI photo-polarimetry (Oudmaijer+ 2001)J/AJ/124/1001 : JHKs photometry of Cha I variables (Carpenter, 2002)J/A+A/409/169 : UBVRI light curves of AA Tau in 1999 (Bouvier+, 2003)J/A+A/463/1017 : B and V light curves of AA Tau (Bouvier+, 2007)J/A+A/467/785 : SuperWASP/ROSAT periodic variable stars (Norton+, 2007)J/A+A/479/827 : UBVR light curves of weak-line T Tauri stars (Grankin+, 2008)J/ApJ/696/870 : Catalina Real-time Transient Survey (CRTS) (Drake+, 2009)J/A+A/508/1313 : Orion pre-main sequence RIJH light curves (Frasca+, 2009)J/A+A/502/883 : I photometry of low mass ONC stars (Rodriguez-Ledesma+, 2009)J/ApJS/191/389 : Photometric monitoring in {sigma} Ori cluster (Cody+, 2010)J/AJ/140/2025 : KH 15D (V582 Mon) VI light curves (Herbst+, 2010)J/ApJS/186/111 : Spitzer observations of Taurus members (Luhman+, 2010)J/ApJ/733/50 : Mid-IR photom. monitoring of the ONC (Morales-Calderon+, 2011)J/ApJ/747/51 : Lagoon Nebula stars.
