NGTS-11 b (TOI-1847 b): A Transiting Warm Saturn Recovered from a TESS Single-transit Event
Gill, S; Wheatley, PJ; Cooke, BF; Jordan, A; Nielsen, LD; Bayliss, D; Anderson, DR; Vines, JI; Lendl, M; Acton, JS (2020-07) -
NGTS-12b: A sub-Saturn mass transiting exoplanet in a 7.53 day orbit
Bryant, EM; Bayliss, D; Nielsen, LD; Veras, D; Acton, JS; Anderson, DR; Armstrong, DJ; Bouchy, F; Briegal, JT; Burleigh, MR (Oxford University Press, 2020-09)We report the discovery of the transiting exoplanet NGTS-12b by the Next Generation Transit Survey (NGTS). The host star, NGTS-12, is a V = 12.38 mag star with an effective temperature of Teff = 5690 ± 130 K. NGTS-12b ... -
NGTS-13b: A hot 4.8 Jupiter-mass planet transiting a subgiant star
Grieves, N; Nielsen, LD; Vines, JI; Bryant, EM; Gill, S; Bouchy, F; Lendl, M; Bayliss, D; Eigmueller, P; Segransan, D (EDP Sciences, 2021-03-01)We report the discovery of the massive hot Jupiter NGTS-13b by the Next Generation Transit Survey (NGTS). The V = 12.7 host star is likely in the subgiant evolutionary phase with logg∗ = 4.04 ± 0.05, Teff = 5819 ± 73 K, ... -
NGTS-14Ab: a Neptune-sized transiting planet in the desert
Smith, AMS; Acton, JS; Anderson, DR; Armstrong, DJ; Bayliss, D; Belardi, C; Bouchy, F; Brahm, R; Briegal, JT; Bryant, EM (EDP Sciences, 2021-02-26)Context. The sub-Jovian, or Neptunian, desert is a previously identified region of parameter space where there is a relative dearth of intermediate-mass planets with short orbital periods. Aims. We present the discovery ... -
NGTS-19b: A high mass transiting brown dwarf in a 17-day eccentric orbit
Acton, JS; Goad, MR; Burleigh, MR; Casewell, SL; Breytenbach, H; Nielsen, LD; Smith, G; Anderson, DR; Battley, MP; Bayliss, D (Oxford University Press, 2021-05-22)We present the discovery of NGTS-19b, a high-mass transiting brown dwarf discovered by the Next Generation Transit Survey. We investigate the system using follow-up photometry from the South African Astronomical Observatory, ... -
