Title: Can infrared photometry predict the best M dwarf planet RV targets?

Abstract: With M dwarfs an ideal target for high precision, high cadence radial velocity searches for Earth-mass planets, the issue of characterizing their intrinsic RV noise has become paramount. Here, we choose to collect high-cadence infrared relative photometry of a set of five M dwarfs with both K2 optical light curves and RV measurements. We ask for five nights for a pilot program of five M dwarf targets observing with WIYN/WHIRC. We will compare the properties of these three datasets (RMS, derivatives, periodigram, etc.) to search for correlations which would allow us to predict the degree of RV jitter for that M dwarf host star. Not only might this comparison reveal new characteristics of the activity of M dwarfs but it could also give planet hunters the power to vet RV targets with photometry from 3-m telescopes or guide them on which targets may require a more strenuous RV observing cadence, simultaneous optical and infrared RV observations or simultaneous photometry.
