Popis: | We report the discovery and characterisation of a super-Earth and a sub-Neptune transiting the bright (K = 8:8), quiet, and nearby (37 pc) M3V dwarf TOI-1266. We validate the planetary nature of TOI-1266 b and c using four sectors of TESS photometry and data from the newly-commissioned 1-m SAINT-EX telescope located in San Pedro Mártir (México). We also include additional groundbased follow-up photometry as well as high-resolution spectroscopy and high-angular imaging observations. The inner, larger planet has a radius of R = 2:37+0:16 -0:12 R and an orbital period of 10.9 days. The outer, smaller planet has a radius of R = 1:56+0:15 -0:13 R on an 18.8-day orbit. The data are found to be consistent with circular, co-planar and stable orbits that are weakly influenced by the 2:1 mean motion resonance. Our TTV analysis of the combined dataset enables model-independent constraints on the masses and eccentricities of the planets. We find planetary masses of Mp = 13:5+11:0 -9:0 M ( Embassy of Mexico in Bern Swiss National Science Foundation (SNSF) Programa de Apoyo a Proyectos de Investigacion e Innovacion Tecnologica (PAPIIT) Universidad Nacional Autonoma de Mexico IN-107518 DGAPA Australian Research Council Fonds de la Recherche Scientifique - FNRS FRFC 2.5.594.09 Swiss National Science Fundation (SNF) - University of Liege Spanish public funds for research ESP2017-87676-2-2 RYC-2012-09913 Spanish Government National Aeronautics & Space Administration (NASA) NASA High-End Computing (HEC) Program through the NASA Baja California, Mexico - Spanish State Research Agency (AEI) MDM-2017-0737 Unidad de Excelencia "Maria de Maeztu"- Centro de Astrobiologia (INTA-CSIC) Junta de Andalucía European Research Council (ERC) 336480 Alfred P.
