    • An Eccentric Massive Jupiter Orbiting a Subgiant on a 9.5-day Period Discovered in the Transiting Exoplanet Survey Satellite Full Frame Images 

      Rodriguez, Joseph E.; Quinn, Samuel N.; Huang, Chelsea X.; Vanderburg, Andrew; Penev, Kaloyan; e.a. (American Astronomical Society, 2019-04)
      We report the discovery of TOI-172 b from the Transiting Exoplanet Survey Satellite (TESS) mission, a massive hot Jupiter transiting a slightly evolved G star with a 9.48-day orbital period. This is the first planet to be ...

    • Hot, rocky and warm, puffy super-Earths orbiting TOI-402 (HD 15337) 

      Dumusque, Xavier; Turner, Oliver; Dorn, Caroline; Eastman, Jason D.; Allart, Romain; e.a. (EDP Sciences, 2019-06)
      Context. The Transiting Exoplanet Survey Satellite (TESS) is revolutionising the search for planets orbiting bright and nearby stars. In sectors 3 and 4, TESS observed TOI-402 (TIC-120896927), a bright V = 9.1 K1 dwarf ...

    • A Pair of TESS Planets Spanning the Radius Valley around the Nearby Mid-M Dwarf LTT 3780 

      Cloutier, Ryan; Eastman, Jason D.; Rodriguez, Joseph E.; Astudillo-Defru, Nicola; Bonfils, Xavier; e.a. (American Astronomical Society, 2020-06)
      © 2020. The American Astronomical Society. All rights reserved We present the confirmation of two new planets transiting the nearby mid-M dwarf LTT 3780 (TIC 36724087, TOI-732, V = 13.07, K s = 8.204, R s = 0.374 R o˙, M ...

    • A System of Three Super Earths Transiting the Late K-Dwarf GJ 9827 at 30 pc 

      Rodriguez, Joseph E.; Vanderburg, Andrew; Eastman, Jason D.; Mann, Andrew W.; Crossfield, Ian J. M.; e.a. (American Astronomical Society, 2018-01)
      We report the discovery of three small transiting planets orbiting GJ 9827, a bright (K = 7.2) nearby late K-type dwarf star. GJ 9827 hosts a 1.62 ± 0.11 R⊕ super Earth on a 1.2 day period, 1.269[subscript -00.089][superscript ...

    • Two Warm, Low-Density Sub-Jovian Planets Orbiting Bright Stars in K2 Campaigns 13 and 14 

      Yu, Liang; Rodriguez, Joseph E.; Eastman, Jason D.; Crossfield, Ian Jm; Shporer, Abraham-Avi; e.a. (American Astronomical Society, 2018-08)
      We report the discovery of two planets transiting the bright stars HD 89345 (EPIC 248777106, V = 9.376, K = 7.721) in K2 Campaign 14 and HD 286123 (EPIC 247098361, V = 9.822, K = 8.434) in K2 Campaign 13. Both stars are ...
