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 su...

Zusammenfassung:	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 (\(
