Telluric absorption lines impact measuring precise radial velocities (RVs)from ground-based, high-resolution spectrographs. In this paper, we simulatethe dependence of this impact on stellar spectral type and extend the work ofthe first paper in this series, which studied a G type star, to a synthetic Mdwarf star. We quantify the bias in precise RV measurements in the visible andnear-infrared (NIR) from the presence of tellurics in a simulated set ofobservations. We find that M dwarf RVs are more impacted by tellurics comparedto G type stars. Specifically, for an M dwarf star, tellurics can induce RVerrors of up to 16 cm/s in the red-optical and in excess of 220 cm/s in theNIR. For a G dwarf, comparable RV systematics are 3 cm/s in the red optical and240 cm/s in the NIR. We attribute this relative increase for M dwarfs stars tothe increased concordance in wavelength between telluric lines and stellarDoppler information content. We compare the results of our simulation to datacollected on Barnard's star from the iSHELL spectrograph at the NASA InfraredTelescope Facility (IRTF). This study was conducted as a follow-up to the NASAprobe mission concept study EarthFinder.
