Reduced flux maps of HD 143811 AB obtained by Gemini/GPI in 2016 and 2019 (left and center) and Keck/NIRC2 in 2022 (right). These images are 2” × 2”. North is up and East is left. The star is at the center of the image behind the coronagraph. Arrows indicates the location of the companion. Intensity scales are linear and vary for each image in order to highlight the companion. -- astro-ph.EP
