The 1-min short cadence interval permitted observations of pressure- or p-mode oscillations ofsolar-like stars, which have typical oscillation periods much less than a half hour. Despite beingdesigned exclusively for the purpose of detecting minute drops in brightness corresponding totransit events, Kepler has proven itself adept at revealing stellar variability over a huge dynamicrange from p-mode oscillations of ⇠10 ppm and transit signatures of ⇠100 ppm, to oscillationsof RR Lyrae stars, which can nearly double their brightness every half day. Figure 2.3 illustratesthe large dynamic range (105.8) of photometric features identified in Kepler light curves withSOC 9.3.

Figure 2.3 a: A Hertzsprung–Russell diagram displaying log luminosity vs. log effective temperaturefor 15,000 stars exhibiting p-mode oscillations observed by Kepler (Huber, 2016). The points are coloredby the amplitudes of the stellar oscillations, which vary from 3 ppm to ⇠3600 ppm, illustrating that theamplitudes vary with the mass and size of the star. The inset shows similar results for ⇠20 stars obtainedprior to 2008. b: Light curve for the RR Lyr star KIC 7671081 exhibiting amplitude modulation via theBlazhko effect. The SOC 9.3 pipeline greatly reduces the distortions of the intrinsic astrophysical signalsin the light curves of high amplitude variable stars compared to SOC 7.0 and earlier codebases.

The Kepler SOC was developed at NASA Ames Research Center over a 12-year period oftime beginning in 2004 and continuing through the primary mission and well into the extendedmission. Three principle factors stimulated significant research and development of new algo-rithmic approaches for virtually every module of the science data processing pipeline: 1) thestellar variability of the main-sequence stars in Kepler’s FOV proved to be twice as large as ex-pected, based on long-term observations of the Sun (Gilliland et al., 2011, 2015), 2) instrumentaleffects caused both by radiation damage and by electronic image artifacts triggered an overabun-dance of false alarms and threatened to overwhelm the system (Caldwell et al., 2010; Coughlinet al., 2014; Mullally et al., 2015), and 3) the interplay of the intrinsic stellar signatures and in-strumental signatures required the development of more sophisticated approaches to identifyingand removing systematic errors than were available in the original pre-launch pipeline design(Jenkins et al., 2012).
