Extended Data Fig. 2: Speckle imaging of SPECULOOS-3.
From: Detection of an Earth-sized exoplanet orbiting the nearby ultracool dwarf star SPECULOOS-3
Result from speckle imaging with the ’Alopeke instrument mounted on the 8-m Gemini-North telescope, on Maunea Kea, Hawai’i. The inset on the top right shows the final image produced by our analysis, which is summarized by the two curves of the main figure. These curves show the sensitivity in two bands (blue = 562 nm and red = 832 nm). The observations reveal there are no companions with a brightness greater than 5 to 6 magnitudes at distances above 0.1” from SPECULOOS-3A, which corresponds to a physical distance of approximately 1.7 AU.
