Wolf 1061 velocities and planet candidates

We detect a 1.36M_{Earth}_ minimum-mass planet with an orbital period P=4.888days (Wolf 1061b), a 4.25M_{Earth}_ minimum-mass planet with orbital period P=17.867days (Wolf 1061c), and a likely 5.21M_{Earth}_ minimum-mass planet with orbital period P=67.274days (Wolf 1061d). All of the planets are of sufficiently low mass that they may be rocky in nature.

The 17.867day planet falls within the habitable zone for Wolf 1061 and the 67.274day planet falls just outside the outer boundary of the habitable zone. There are no signs of activity observed in the bisector spans, cross-correlation FWHMs, calcium H & K indices, NaD indices, or H{alpha} indices near the planetary periods. We use custom methods to generate a cross-correlation template tailored to the star.
