Distribution of our found planets in period–radius space (left) and instellation–radius space (right). Each planet and its associated errors are are marked with the red points, while the background grid shows the peak occurrence rate fpeak in each bin of the grid. Regions where our average sensitivity is < 10% are highlighted in pink. The top and leftmost panels show the cumulative fpeak distributions from each map. We note that these distributions are not representative of the full occurrence rates, and differ because planets may find themselves in different regions of sensitivity based on their instellation and period. -- astro-ph.EP

TESS Planet Occurrence Rates Reveal the Disappearance of the Radius Valley Around Mid-to-Late M Dwarfs

by Keith CowingMarch 2, 2026March 2, 2026

We present the deepest systematic search for planets around mid-to-late M dwarfs to date. We have surveyed 8134 mid-to-late M dwarfs observed by TESS with a custom built pipeline and […]
