High-Spatial-Resolution K-Band Imaging of Select K2 Campaign Fields
  NASA's K2 mission began observing fields along the ecliptic plane in 2014.
Each observing campaign lasts approximately 80 days, during which
high-precision optical photometry of select astrophysical targets is collected
by the Kepler spacecraft. Due to the 4 arcsec pixel scale of the Kepler
photometer, significant blending between the observed targets can occur
(especially in dense fields close to the Galactic plane). We undertook a
program to use the Wide Field Camera (WFCAM) on the 3.8 m United Kingdom
InfraRed Telescope (UKIRT) to collect high-spatial-resolution near-infrared
images of targets in select K2 campaign fields, which we report here. These 0.4
arcsec resolution K-band images offer the opportunity to perform a variety of
science, including vetting exoplanet candidates by identifying nearby stars
blended with the target star and estimating the size, color, and type of
galaxies observed by K2.
