cds-question@unistra.frexoplanetsm-starsvisible-astronomystellar-massesstellar-radiiWe present an analysis of a volume-complete sample of 363 mid-to-late M-dwarfs within 15pc of the Sun with masses between 0.1 and 0.3M{sun} observed by TESS within sectors 1-42. The median stellar mass of the sample is 0.17M{sun}. We search the TESS light curves for transiting planets with orbital periods below 7 days and recover all six known planets within the sample, as well as a likely planet candidate orbiting LHS-475. Each of these planets is consistent with a terrestrial composition, with planet radii between 0.91 and 1.31R{Earth}. We characterize the transit detection sensitivity for each star as a function of planet radius, insolation, and orbital period. We obtain a cumulative occurrence rate of 0.61_-0.19_^+0.24^ terrestrial planets per star with radii above 0.5R{Earth} and orbital periods between 0.4 and 7days. We find that for comparable insolations, planets larger than 1.5R{Earth} (sub-Neptunes) are significantly less abundant around mid-to-late M dwarfs compared to earlier-type stars, while the occurrence rate of terrestrial planets is comparable to that of more massive M-dwarfs. We estimate that overall, terrestrials outnumber sub-Neptunes around mid-to-late M-dwarfs by 14 to 1, in contrast to GK dwarfs, where they are roughly equinumerous. We place a 1{sigma} upper limit of 0.07 planets larger than 1.5R{Earth} per star within the orbital period range of 0.5-7days. We find evidence for a downturn in occurrence rates for planet radii below 0.9R{Earth}, suggesting that Earth-sized and larger terrestrials may be more common around mid-to-late M-dwarfs.2023AJ....165..265Mhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/AJ/165/265CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/ApJ/757/112 : Stellar diameters.
