A High-Precision NIR Survey for RV Variable Low-Mass Stars

We present the results of a precise near-infrared (NIR) radial velocity (RV) survey of 32 low-mass stars with spectral types K2-M4 using CSHELL at the NASA IRTF in the $K$-band with an isotopologue methane gas cell to achieve wavelength calibration and a novel iterative RV extraction method. We surveyed 14 members of young ($\approx$ 25-150 Myr) moving groups, the young field star $\varepsilon$ Eridani as well as 18 nearby ($
