cds-question@unistra.frmultiple-starsexoplanetsThe Transiting Exoplanet Survey Satellite (TESS) has been highly successful in detecting planets in close orbits around low-mass stars, particularly M dwarfs. This presents a valuable opportunity to conduct detailed population studies to understand how these planets depend on the properties of their host stars. The previously observed radius valley in Sun-like stars has also been observed among M dwarfs; however, how its properties vary when compared with more massive stars remains uncertain. We select the volume limited Bioverse stellar catalog, with precise photometric stellar parameters, which was cross-matched with the planet catalog consisting of TESS objects of interests (TOI) candidates and confirmed planets. We detect the radius valley around M dwarfs at a location of 1.64+/-0.03 R_{Earth}_ and with a depth of approximately 45%. The radius valley among GKM stars scales with stellar mass as Rp{prop.to M*^0.15+/-0.04^. The slope is consistent, within 0.3{sigma}, with those around Sun-like stars. For M dwarfs, the discrepancy is 3.6{sigma} with the extrapolated slope from the Kepler FGK sample, marking the point where the deviation from previous results begins. Moreover, we do not see a clear shift in the radius valley between early and mid M dwarfs. The flatter scaling of the radius valley for lower-mass stars suggests that mechanisms other than atmospheric mass loss through photoevaporation may shape the radius distribution of planets around M dwarfs. A comparison of the slope with various planet formation and evolution models leads to a good match with pebble accretion models including water worlds, indicating a potentially different regime of planet formation that can be probed with exoplanets around the lowest-mass stars.2025A&A...703A...8Mhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/703/A8CatalogResearchIsServedByTAP VizieR generic
