Description
Rapid optical variability in infrared and optically bright blazars blazars are extreme examples of the phenomena known as active galactic nuclei (AGN). The defining characteristics of blazars are a featureless (or nearly featureless) optical continuum, large amplitude and highly variable polarization, and large amplitude continuum variability at all wavelengths. Their weak/absent discrete spectral features leave US with only continuum variability and/or polarization variability as a diagnostic of the emission mechanisms at work in these objects. The blazar class of objects is comprised of the BL lacertae (BL LAC) objects and the flat spectrum radio quasars (fsrq). The difference between a BL LAC and a fsrq lies primarily in the strength of any emission lines present in the spectrum. In the BL LAC objects, emission lines are nonexistent or are present with equivalent WIDTHS5 a. Blazar spectral energy distributions display a two-bump structure. At low energies there is a peak arising from synchrotron emission in the jet, while at higher energies the peak is believed to be the result of inverse compton scattering of photons off of relativistic electrons in the jet. The frequency of the synchrotron peak divides blazars into sub-classes: low frequency peaked (LBL), intermediate frequency peaked (IBL), and high frequency peaked (HBL). Long cadence observations of a sample of optical and IR bright blazars identified in the F6 and F7 field of the K2 mission are proposed. The source sample will be comprised of blazars with KEP magnitude
