Image Details
Caption: Figure 7.
Top left: our 5σ contrast curves and the reconstructed speckle images observed using the Zorro speckle instrument on the Gemini South 8 m telescope. Sensitivity is quoted on the vertical axis in magnitudes relative to the host star, as a function of angular separation on the horizontal axis. Inset: a cutout of our image, centered on the target star TOI 560. Top right: same as top-left, showing the 5σ detection sensitivity and speckle autocorrelation functions from the SOAR observations. Bottom: same as the top two panels, showing our sensitivity of the Gemini/NIRI observations to companion stars, as a function of separation from the host star. No visual companions are seen anywhere in all of our high-contrast imaging data, and the star appears single.
