High-resolution imaging of TOI-2081. Top: adaptive optics images of TOI-2081 taken with the ShARCS camera on the Shane 3-meter telescope at the Lick Observatory. For each image, we also present a contrast curve generated by calculating the median values (solid lines) and root-mean-square errors (blue, shaded regions) in annuli centered on each target, where the bin width of each annulus is equal to the full width at half maximum of the point spread function. The observations rule out the presence of a possible nearby contaminant companion. Bottom: high angular resolution speckle imaging of TOI-2081 in I filter using SAI-2.5 m telescope. The observation rules out the presence of a possible nearby contaminant companion. The structure in this contrast curve is due to the first derivative discontinuity in the frequency mask that is used to compute the autocorrelation. This discontinuity generates rings at characteristic distances from the center, which then have a minor effect on the detection limit.
