      Jeffers, S. V.; Dreizier, S.; Barnes, J. R.; Haswell, C. A.; Nelson, R. P.; Rodríguez, E.; López González, M. J.; Morales, N.; Luque, R.; Zechmeister, M.; Vogt, S. S.; Jenkins, James Stewart; Palle, E.; Berdinas, Z. M.; Coleman, G.; Díaz, M. R.; Ribas, I.; Jones, H.R.A.; Butler, R. P.; Tinney, C. G.; Bailey, J.; Carter, B. D.; O'Toole, S.; Wittenmyer, R. A; Crane, J. D.; Feng, F.; Shectman, S. A.; Teske, J.; Reiners, A.; Amado, P. J.; Anglada Escude, G. (Amer Assoc Advancement Science, 2020)
      The closet exoplanets to the Sun provide opportunities for detailed characterization of planets outside the Solar System. We report the discovery, using radial velocity measurements, of a compact multiplanet system of ...
    • TESS Reveals a short-period sub-neptune sibling (HD 86226c) to a known long-period giant planet 
      Teske, Johanna; Díaz, Matías R.; Luque, Rafael; Močnik, Teo; Seidel, Julia V.; Fernández Otegi, Jon; Feng, Fabo; Jenkins, James S.; Pallè, Enric; Ségransan, Demien; Udry, Stéphane; Collins, Karen A.; Eastman, Jason D.; Ricker, George R.; Vanderspek, Roland; Latham, David W.; Seager, Sara; Winn, Joshua N.; Jenkins, Jon M.; Anderson, David R.; Barclay, Thomas; Bouchy, François; Burt, Jennifer A.; Paul Butler, R.; Caldwell, Douglas A.; Collins, Kevin I.; Crane, Jeffrey D.; Dorn, Caroline; Flowers, Erin; Haldemann, Jonás; Helled, Ravit; Hellier, Coel; Jensen, Eric L.

      The Transiting Exoplanet Survey Satellite mission was designed to find transiting planets around bright, nearby stars. Here, we present the detection and mass measurement of a small, short-period (≈4 days) transiting ...
    • The chemical inventory of the planet-hosting disk PDS 70 
      Facchini, Stefano; Teague, Richard; Bae, Jaehan; Benisty, Myriam; Keppler, Miriam; Isella, Andrea (IOP, 2021)
      As host to two accreting planets, PDS 70 provides a unique opportunity to probe the chemical complexity of atmosphere-forming material. We present ALMA Band 6 observations of the PDS 70 disk and report the first chemical ...
