![AU mic b light curves from TESS and Spitzer AU mic b light curves from TESS and Spitzer IRAC at 4.5 μm (purple filled circles). The transit model (orange curve) includes a photometric model that accounts for the stellar activity modelled with a Gaussian Process (GP), which is subtracted from the data before plotting. The frequent flares from the stellar surface are removed with an iterative sigma-clipping.](/sites/default/files/styles/crop_square_2_2_to_320px/public/images/news/Figure.png?h=16996102&itok=wybi-4nX)
AU Microscopii (AU Mic) is the second closest pre-main-sequence star, at a distance of 9.79 parsecs and with an age of 22 million years . AU Mic possesses a relatively rare and spatially resolved edge-on debris disk extending from about 35 to 210 astronomical units from the star , and with clumps exhibiting non-Keplerian motion . Detection of newly formed planets around such a star is challenged by the presence of spots, plage, flares and other manifestations of magnetic ‘activity’ on the star . Here we report observations of a planet transiting AU Mic. The transiting planet, AU Mic b, has
