cds-question@unistra.frexoplanetsvisible-astronomyspectroscopyradial-velocityWe present a radial velocity (RV) analysis of TOI-1136, a bright Transiting Exoplanet Survey Satellite (TESS) system with six confirmed transiting planets, and a seventh single-transiting planet candidate. All planets in the system are amenable to transmission spectroscopy, making TOI-1136 one of the best targets for intra-system comparison of exoplanet atmospheres. TOI-1136 is young (~700Myr), and the system exhibits transit timing variations (TTVs). The youth of the system contributes to high stellar variability on the order of 50m/s, much larger than the likely RV amplitude of any of the transiting exoplanets. Utilizing 359 High Resolution Echelle Spectrometer and Automated Planet Finder RVs collected as part of the TESS-Keck Survey, and 51 High-Accuracy Radial velocity Planetary Searcher North RVs, we experiment with a joint TTV-RV fit. With seven possible transiting planets, TTVs, more than 400 RVs, and a stellar activity model, we posit that we may be presenting the most complex mass recovery of an exoplanet system in the literature to date. By combining TTVs and RVs, we minimized Gaussian process overfitting and retrieved new masses for this system: (mb-g=3.50_-0.7_^+0.8^, 6.32_-1.3_^+1.1^, 8.35_-1.6_^+1.8^, 6.07_-1.01_^+1.09^, 9.7_-3.7_^+3.9^, 5.6_-3.2_^+4.1^M{Earth}). We are unable to significantly detect the mass of the seventh planet candidate in the RVs, but we are able to loosely constrain a possible orbital period near 80days. Future TESS observations might confirm the existence of a seventh planet in the system, better constrain the masses and orbital properties of the known exoplanets, and generally shine light on this scientifically interesting system.2024AJ....167...70Bhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/AJ/167/70CatalogResearchIsServedByTAP VizieR generic servicerelated-toI/337 : Gaia DR1 (Gaia Collaboration, 2016)J/ApJS/197/8 : Kepler candidate multiple transit planets (Lissauer+, 2011)J/ApJ/805/175 : Keck and APF radial velocities of HD7924 (Fulton+, 2015)J/A+A/584/A72 : Transiting rocky planet at 6.5pc from Sun (Motalebi+ 2015)J/ApJ/809/77 : Transiting Exoplanet Survey Satellite (Sullivan+, 2015)J/AJ/152/204 : HARPS-N radial velocities of HD179070 (Lopez-Morales+, 2016)J/AJ/152/158 : Final Kepler transiting planet search DR25 (Twicken+, 2016)J/ApJ/834/17 : Mass & radius planets, moons, low mass stars (Chen+, 2017)J/AJ/154/226 : Photometry and radial velocities of K2-131 (Dai+, 2017)J/AJ/154/109 : California-Kepler Survey.
