G.; Durkan, S.; Lazar, J.; Papp, I.; Sari, P. (IOP Publishing Ltd, 2019-01-02)
    We report the discovery of HATS-70b, a transiting brown dwarf at the deuterium burning limit. HATS-70b has a mass of M_{p} = 12.9{{-1.6}^{+1.8} M_{Jup} and a radius of R_{p} = 1.384_{{-0.074} {+0.079}} R_{Jup}, residing ...
  • KELT-22Ab: A Massive, Short-Period Hot Jupiter Transiting a Near-Solar Twin 

    Labadie-Bartz, Jonathan; Rodriguez, Joseph E.; Stassun, Keivan G.; Ciardi, David R.; Penev, Kaloyan; Johnson, Marshall C.; Gaudi, B. Scott (IOP Publishing Ltd, 2019-01-21)
    We present the discovery of KELT-22Ab, a hot Jupiter from the KELT-South survey. KELT-22Ab transits the moderately bright (V ~ 11.1) Sun-like G2V star TYC 7518-468-1. The planet has an orbital period of P = 1.3866529 ± ...
  • An Eccentric Massive Jupiter Orbiting a Subgiant on a 9.5-day Period Discovered in the Transiting Exoplanet Survey Satellite Full Frame Images 

    Rodriguez, J. E.; Quinn, S. N.; Huang, C. X.; Vanderburg, A.; Penev, Kaloyan; Brahm, R.; Jordán, A. (Institute of Physics Publishing, 2019-05)
    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 ...
  • HATS-39b, HATS-40b, HATS-41b, and HATS-42b: Three Inflated Hot Jupiters and a Super-Jupiter Transiting F Stars
