Abstract
We present Very Large Array observations at 33.0 GHz that detect emission coincident with Eridani to within 007 (0.2 au at the distance of this star), with a positional accuracy of 005. This result strongly supports the suggestion of previous authors that the quiescent centimeter emission comes from the star and not from a proposed giant exoplanet with a semimajor axis of ∼10 (3.4 au). The centimeter emission is remarkably flat and is consistent with optically thin free–free emission. In particular, it can be modeled as a stellar wind with a mass-loss rate of the order of 6.6 × 10−11 yr−1, which is 3300 times the solar value, exceeding other estimates of this star's wind. However, interpretation of the emission in terms of other thermal mechanisms like coronal free–free and gyroresonance emission cannot be discarded.
